Requested light output
Control gear Arc power Light output
Actual level
IEC
Figure 2 – Control gear directly operating a light source

Figure 2 shows how the various levels lead to light output. The maximum (light) output level of

a control gear is referred to as 100 %. All levels are specified in a relative way. Physically

there is a minimum that the control gear can supply whilst there is still light output. This is

known as the physical minimum level (PHM).
NOTE PHM is control gear specific, and is greater than 0.

9.2.2 Control gear phases
9.2.2.1 General

Depending on the light source various phases of operation can be identified within a control

gear. In general these are as follows.
9.2.2.2 Standby

During this phase, the lamp is off and only in this phase both “targetLevel” and “actualLevel”

are 0.
9.2.2.3 Startup

Startup is a transitional phase changing from standby to normal operation or failure. This

phase is sometimes noticeable as a delay. Examples are:

• preheat: the lamp is heated to prepare for ignition. This is typically seen for fluorescent

light sources;

• ignition: the lamp is ignited. This is typically seen for HID light sources and fluorescent

light sources after preheat;
• power stage preparation.
For further information and exceptions refer to 9.16.3.
9.2.2.4 Normal operation

While in normal operation the lamp is emitting light and can be operated as expected.

For further information and exceptions refer to 9.16.3.
9.2.2.5 Failure
During the failure phase the lamp cannot be operated as expected.
For further information and exceptions refer to 9.16.3.
9.3 Dimming curve

Replace, in the last sentence of the fourth paragraph, "reproduceablility" with "reproducibility".

Table 2

Replace, in the first column and first row,"Arc power level" with "Level" as follows:

Level 1 60 85 126 145 170 195 216 229 243 254
Minimum value 0,05 0,25 0,50 2,00 3,93 7,00 15,00 27,28 40,00 63,53
Nominal value 0,10 0,50 0,99 3,04 5,10 10,09 19,97 35,43 50,53 74,05 100,00
Maximum value 0,20 1,00 2,00 4,50 7,50 15,0 30,00 52,09 71,00 86,14
9.5.1 General
Replace the sixth paragraph with the following new paragraph:

During a process of fading up, “actualLevel” shall be incremented at a time corresponding to

the intersection of an ideal fading curve with the mid-point between “actualLevel” and

---------------------- Page: 8 ----------------------
IEC 62386-102:2014/AMD1:2018 – 7 –
© IEC 2018

“actualLevel” + 1. Likewise, when fading down, “actualLevel” shall be decremented at a time

corresponding to the intersection of an ideal fading curve with the mid-point between

“actualLevel” and “actualLevel” – 1. Figure 4 illustrates this, and applies for fades started

using either fade time or fade rate.
Replace the ninth paragraph with the following new paragraph:

If a lamp is to be lit at the beginning of the fade and dimmed to a certain value, the step from

0x00 to “minLevel” shall not contribute to the fade time. This means that the fade time starts

when the startup phase has finished.
9.5.3 Fade rate
Replace the first paragraph with the following new sentence:
The fade rate shall be according to Table 5:
9.5.4 Extended fade time
Delete the second paragraph.
Replace, after Table 7, the text with the following new text:

On execution of “SET EXTENDED FADE TIME (DTR0)” the control gear shall set the following

values based on “DTR0”. The format used shall be 0YYYAAAAb, where YYYb equals the fade

time multiplier, and AAAAb the fade time base: The resulting fade time shall be monotonically

increasing when the base time increases.
• If “DTR0” > 0100 1111b:
– “extendedFadeTimeBase” shall be set to 0;

– “extendedFadeTimeMultiplier” shall be set to 0 ms, effectively setting the fade time to 0 s

meaning no fade (as quickly as possible). The transition from “actualLevel” to

“targetLevel” shall take place immediately and the light output shall be adjusted as

quickly as possible, meaning less than 0,8 s which represents the maximum fade time

for “fadeTime” = 1 (see Table 4).
• In all other cases:
– “extendedFadeTimeBase” shall be set to AAAAb;
– “extendedFadeTimeMultiplier” shall be set to YYYb.

The extended fade time can be queried using “QUERY EXTENDED FADE TIME”. The answer

shall be 0 YYY AAAAb, where YYYb equals “extendedFadeTimeMultiplier” and AAAAb equals

“extendedFadeTimeBase”.
9.5.5 Using the fade time
Replace the third paragraph with the following new paragraph:

Since the extended fade time also supports fade times below 0,7 s that might not be realised

by all control gear and light source combinations, such control gear may simply adjust the

light output as quickly as possible when an extended fade time is requested that it physically

cannot support. However, it should respond as if the fade has finished within the requested

time.
9.5.6 Using the fade rate
Replace the content of 9.5.6 with the following new subclauses:
---------------------- Page: 9 ----------------------
– 8 – IEC 62386-102:2014/AMD1:2018
© IEC 2018
9.5.6.1 Fading with “UP” and “DOWN” commands
Commands “UP” and “DOWN” shall start a 200 ms ± 20 ms fade.

“targetLevel” shall be calculated on the basis of the “actualLevel” using the applicable fade

rate. After the 200 ms fade has expired, the calculated target level shall be reached.

NOTE 1 Since the fade rate is used, it is possible to reach “minLevel” or “maxLevel” before the end of the fade.

This does not result in the “fadeRunning” bit being cleared.

NOTE 2 Because there are fade rate tolerances, different control gear can react to commands that use the fade

rate at slightly different effective rates. Consequently, after the processing of these relative dimming commands,

different gear might have different values for “targetLevel” (and therefore also for “actualLevel” and “lastLightLevel”).

9.5.6.2 Fading with “CONTINUOUS UP” and “CONTINUOUS DOWN” commands

Command “CONTINUOUS UP” shall set “targetLevel” to “maxLevel” and start a fade using the

applicable fade rate. The fade shall stop when “maxLevel” is reached.

Command “CONTINUOUS DOWN” shall set “targetLevel” to “minLevel” and start a fade using

the applicable fade rate. The fade shall stop when “minLevel” is reached.

Upon execution of either a “CONTINUOUS UP” or “CONTINUOUS DOWN” instruction at least

one step shall be made, unless this is precluded by the values of "minLevel" or "maxLevel".

Refer to 9.5.9 for stopping a fade before reaching “minLevel” or “maxLevel”.

NOTE 1 In contrast to the “UP” and “DOWN” instructions, it is not possible to reach “minLevel” or “maxLevel”

before the end of the fade. Therefore, “fadeRunning” bit is going to be cleared at the end of a fade.

NOTE 2 Similar to the “UP” and “DOWN” instructions, different gear might end up with different values for

“targetLevel”, “actualLevel” and “lastLightLevel” after the fade has been stopped ahead of time (e.g. via

DAPC(MASK)).
9.5.7 Behaviour during a fade
Replace the title of Subclause 9.5.7 with the following new title:
9.5.7 System response to changes during a fade
9.5.8 Behaviour during start-up

Replace the existing Subclause 9.5.8 including its title with the following new title and new

text:
9.5.8 System response to changes during standby and start-up

If a fade is initiated during standby, the fade process shall be pended with “actualLevel” equal

to “minLevel” during the startup phase. The reaction to level commands shall be the same as if

the lamp(s) were operating at “minLevel”.

If a fade is initiated during start-up, the fade process shall be pended at “actualLevel”. The

reaction to level commands shall be the same as if the lamp(s) were operating at
“actualLevel”.
The fade shall start:
• as soon as “lampOn” is TRUE, or
• in the case of total lamp failure, as soon as “lampFailure” is confirmed TRUE.
For further information on “lampOn” and “lampFailure” see 9.16.3 and 9.16.4.

© IEC 2018
9.5.9 Stopping a fade
Replace, in the first paragraph, “reception” with “execution”.
9.6 Min and max level

Add, at the end of the third paragraph and at the end of the fifth paragraph, the following new

sentence:
As a consequence, “limitError” shall be set to TRUE.
9.7.1 General
Replace the first sentence with the new following new sentence:

A control gear shall check the device addressing scheme to see if it is addressed by a

command. The control gear shall execute the command, unless any of the following
conditions hold:

Add, in the first paragraph, at the end of the fifth bulleted list item ("The command is not

defined") the following new text:
(e.g. reserved command).
9.7.3 Level instructions initiating a fade
Add, after the last dashed item, the following new dashed item:
– “CONTINUOUS UP”, “CONTINUOUS DOWN”
9.8.1 General
Replace the first sentence with the following new sentence:

The requirements of IEC 62386-101:2014 and IEC62386-101:2014/AMD1:2018, 9.4 apply with

the following additions.
9.8.2 Command iteration of “UP” and “DOWN” commands

Replace, in the first paragraph, the second sentence with the following new sentence:

Upon execution of the first instruction of such an iteration, unless this is precluded by the

values of “minLevel” or “maxLevel”, one step (final “targetLevel” = calculated “targetLevel”±1)

shall be made.
Replace the second paragraph with the following new paragraph:

After that first step, the 200 ms fade shall start using the applicable fade rate. Subsequent

steps shall be executed at intervals determined by the applicable fade rate, as long as the

iteration continues. Every “UP” or “DOWN” instruction executed as a part of the iteration shall

cause the 200 ms fade time to be restarted and “targetLevel” to be recalculated accordingly.

The transition of “actualLevel” shall occur according to 9.5.1 and Figure 4, with the first such

transition, excluding the initial step, occurring at a time of 1/(2* “fadeRate”) after execution of

the first “UP” and “DOWN” command.
Replace Figure 5 with the following new Figure 5:

9.8.3 DAPC SEQUENCE (deprecated)
Replace, in the second paragraph, “reception” with “execution”.
Replace, after the NOTE, the existing text with the following new text:

The DAPC sequence shall end if 200 ms elapse without the control gear accepting a

“DAPC (level)” command. The DAPC sequence shall be aborted on execution of an indirect

arc power control command. “ENABLE DAPC SEQUENCE” accepted during DAPC command
iteration, shall be discarded.

While the DAPC sequence is active, each execution of a “DAPC (level)” command shall start a

200 ms fade.

Since the DAPC sequence uses a fade time of 200 ms that might not be realised by all control

gear and light source combinations, such gear may simply adjust the light output as quickly as

possible. However, it should respond as if the fade has finished within the requested time.

9.9.4 Operating mode 0x80 to 0xFF: manufacturer specific modes
Add, at the end of the first bulleted list item, the following new text:

Replace, in the first sentence of the seventh paragraph, "identificaton number byte 7" with

"identification number byte 7" and "prefereably" with "preferably".
Replace the NOTE with the following new NOTE:

NOTE As an example there might be a product containing three logical devices with three different short

addresses. Each of these control gear has the same GTIN and identification number, each reports as number of

devices the value 3 and the index of the three control gear is reported as 0, 1 or 2 respectively. Reading location

0x1A using broadcast yields a backward frame according to IEC 62386-101:2014 and IEC62386-

101:2014/AMD1:2018, 9.5.2 (overlapping backward frame).
9.12 System failure
Replace the first sentence with the following new sentence:
If the control gear detects a system failure (see IEC 62386-101:2014 and

IEC62386-101:2014/AMD1:2018, 4.11) and “systemFailureLevel” is not MASK, “targetLevel”

shall be calculated on the basis of “systemFailureLevel”.
9.13 Power on
Replace the first sentence with the following new sentence:

After an external power cycle (see IEC 62386-101:2014 and IEC62386-101:2014/AMD1:2018

4.11.1), the device shall retain its most recent configuration, with the following exceptions:

Add after the last bulleted list item, the following new list item:

• All variables mentioned in Table 14 shall be set to the value indicated in the power on

value column. The variables that are marked with “no change” in the power on value

column shall not be considered. The variables defined in implemented Parts 2xx shall

be included.
Replace, in the third paragraph, “received” with “accepted”.
Replace the fourth paragraph with the new following paragraph:

If “GO TO SCENE (sceneNumber)” where the value of the scene equals MASK is accepted, the

control gear shall discard the command and continue as if no level control command has been

accepted.
Replace, in the fifth paragraph, “received” with “executed”.
Replace, in the seventh paragraph, “received” with “accepted”.
Table 11

Replace the header of the first column "Power on behavior" with the following new header.

Power on system response
Replace NOTE 3 with the following new text:

It is possible that a system failure is detected before the power on level has been reached. If

“systemFailureLevel” is not MASK, the “targetLevel” is recalculated on the basis of

“systemFailureLevel” and the power on level shall not be activated.
Add, in the last paragraph, after "IEC 62386-101", the following new text:
