Unit Specs & Health Checks
OSIR Transmitter
Specified ranges (supply dependant): 90-260VAC,
24-30VDC, 30-48VDC). For suspected power issues
ensure user supply is appropriate & consistent. If
using VDC ensure minimum 24V 5A supply is
present or the actuator cleaning will not operate.
If using AC power you can check the power supply
for faults by reading the DC +/- terminals with a
multimeter set to DC. This terminal will produce 15-
16VDC stable. If this value is lower or inconsistent
you may a problem with the internal power supply.
Unit performance will be affected if the unit detects
voltage below 9VDC. If ‘V in chk’ is on the unit will
trigger its failsafe routine. If V in chk is off the unit will
display V fail on the LCD.
Transducers
The Transducer power (red wire) should draw
8-10VDC. If this figure is too high or too low check
ORCA power & supplied power as above.
Disconnect transducer from amplifier.
There should be no open circuits between wires.
Resistances between transducer wires (approximate
values):
Blue - White 32kohm
Black - Blue 15.6kohm
Black - Red 1-2Mohm (or OV / high resistance)
Black - White 15.6kohm
Black - Blue 2kohm
Blue - Brown 8kohm
Black - Brown 10kohm
Note: Lines 1 & 2 add to total of 10kohm
If any are open circuit check wiring connections or
there may be a problem with the transducer.
Transducer problems may exhibit via the amplifier
protecting itself against high current draw - measure
resistance across transducer: Red and DC:+
terminals on the amplifier while the transducer
disconnected and then connected. If the resistance
increases dramatically there is potentially a wiring or
transducer problem.
OSIRSCA (Electric Actuator)
Actuator position - disconnect the actuator wires and
read for the following values:
Default (pole should be vertical)
Peak extension (default parameters)
Voltage draw during swing out:in - at the terminals (all
wires must be connected to amplifier).
Black - Blue 4kohm (approx)
Blue - Brown 6kohm (approx)
Black - Brown 10kohm
Note: Lines 1 & 2 add to total of 10kohm
Green - Yellow 26VDC: -26VDC
Note: The 'Actuator' LED turns on during the swing
process. If the swing fails the light stays on.
