IES PowerModule Operators’ Manual v1.4 Isine 11
The process is in three parts; setting a current limit,
choosing any priority channels, and activating
current limiting as described below:
6.11.1 To set-up maximum current levels:
1. Press INST.
2. Press Ð or Ï to choose LINE
PARAMETERS menu. Press ENT.
3. The screen shows:
LINE V[240]
I:40 FREQ:50
4. Press Ï or Ð to set the typical voltage of
the mains supply (shown in square
brackets).
5. Press Î to select maximum current for
the module (or per phase for the PM6),
and adjust the level using Ï and Ð.
6. Press Î to select frequency and press Ï
or Ð to switch between 50Hz or 60Hz.
7. Press ENT to leave the menu and record
the changes or EXIT (to leave the
previous settings unchanged).
6.11.2 To set-up priority channels:
1. Press CONF.
2. The screen shows the individual channel
number (or T if the dimmer set-up scheme
copies characteristics to all dimmers in the
rack) and gives access to all configuration
options.
3. Press Ï or Ð to set the channel number
required, followed by Î repeatedly to
select PRIORITY option shown as follows:
CONFIG: CH: T
PRIORITY: [NO.]
4. Press Ï or Ð to select this channel for
priority operation (either YES for priority or
NO for normal operation).
Note: If set to No, the dimmer will take part in a
general lowing of intensity if the preset
maximum current (maximum demand) for
the phase in this dimmer rack is
exceeded. If set to Yes, the dimmer will
remain at its level, and others will reduce
in level to maintain a maximum phase
current.
5. Press ENT to leave the menu and record
the changes or EXIT (to leave the
previous settings unchanged).
6.11.3 To activate current limitation:
1. Press INST.
2. Press Ð or Ï to choose GENERAL
SETTINGS menu. Press ENT.
3. Press Ð or Ï to choose CURRENT LIMIT
menu. Press ENT.
4. The screen shows:
GENERAL
CUR.LIMIT: [ON]
5. Press Ï or Ð to set the current limiting
function either ON or OFF (shown in
square brackets).
6. Press ENT to leave the menu and record
the changes or EXIT (to leave the
previous settings unchanged).
6.12 Voltage regulation
Voltage regulation is a software feature which
maintains the dimmed level of channels in the event
of the mains supply fluctuating (e.g. when power is
supplied from a generator source or a high-
impedance main). The dimmer’s incoming voltage is
measured, and if it diverts from the anticipated
incoming voltage, the dimmer will adjust the output
accordingly to maintain a constant voltage at the
output. The dimmer will maintain output to about 1V
for every 10V input voltage swing. This feature does
not maintain the voltage of full-on dimmer channels,
as the regulation circuit can only work with sufficient
voltage headroom. Programming involves two
stages, firstly setting the nominal voltage, and
secondly activating the voltage regulation software.
6.12.1 To set nominal voltage
1. Press INST.
2. Press Ð or Ï to choose LINE
PARAMETERS menu. Press ENT.
3. The screen shows:
LINE V[230]
I:44 FREQ:50
4. Press Ï or Ð to set the voltage expected
(shown in square brackets).
5. Press ENT to leave the menu and record
the changes or EXIT (to leave the
previous settings unchanged).
6.12.2 To activate voltage regulation
1. Press INST.
2. Press Ð or Ï to choose GENERAL
SETTINGS menu. Press ENT.
3. Press Ð or Ï to choose VOL.
REGULATION menu. Press ENT.
4. The screen shows:
