IES PowerModule Operators’ Manual v1.4 Isine 16
8.2.6 Lamp filaments are noisy
Replace the lamp with a new lamp, and in the case
of 110V Parlamps, try the circuit with a different
manufacturer’s lamp, as some lamps are noisy even
on switched mains supplies.
8.2.7 Dimmers work, but DimSTAT doesn’t
recognise all or some dimmers
Check the DMX network to ensure 2-pair cable is
used and correctly connected throughout. If a DMX
booster/isolator unit is used in the network, check
that it supports bi-directional data on pins 4 and 5.
8.2.8 Voltage regulation is not operating properly
The PowerModule uses a relative measurement of
mains voltage in the general operation of the dimmer
circuit, in the status reporting system, fault detection
and reporting, and output voltage compensation. For
accurate measurement and operation, the incoming
mains supply voltage at the dimmer is calibrated at
the factory. If this calibration is wrong, the voltage-
related parameters will be affected. The solution is
to recalibrate the PowerModule.
Note: IMPORTANT. This set-up procedure may
only be carried out by a qualified electrical
engineer as it involves an accurate
measurement of the mains supply.
8.2.9 To calibrate line voltage
This requires a true RMS digital voltmeter, and a
safe means of connecting the voltmeter to the
dimmer’s supply. If the mains supply is known to
have a high impedance, it is advisable to take the
measurement under normal operating loads so that
voltage drop in the supply can be accommodated in
the measurement.
1. Measure the voltage of the PowerModule
power supply.
2. Press INST.
3. Press Ð or Ï to choose CALL.VOLTAGE
menu. Press ENT.
4. The screen shows:
SERV CODE ????
ENTER ↵ ÅÇÈÆ
4. Press Ï to set the first number to ‘3’ and
press Î to enter the other digits ‘4’, ‘1’,
‘5’. The screen now shows:
L-1 L-2 L-3
[242] --- ---
Note: The screen shows L-1, L-2 and L-3 for the
three-phase PM6 PowerModule.
5. Press Ð and Ï to adjust the voltage to
match the voltage measured at the supply.
Continue with the other two phases in the
case of the PM6.
6. Press ENT to leave the menu and record
the changes or EXIT (to leave the
previous settings unchanged).
