Problem/Symptom
Possible Cause
Solution
No power to any of the six outputs
1) No or low (
2) Bad power input ground connection
3) Defective unit.
1) Remove protective plastic cover &
place a dc voltmeter or DMM across
PDS-100 positive & negative power
input studs to verify input voltage. If
no voltage check for blown or tripped
input fuse/circuit breaker.
2) If no power to PDS-100 input and
fuse/breaker is OK, check for loose
ground cable.
3) Contact Kussmaul for RMA.
Load Group set for timed disconnect
turns off too soon
1) DIP switches not set correctly
2) Battery voltage is dropping below
10.0 VDC causing activation of Master
Low Voltage Shutdown circuit
3) Unit may have been reset to Factory
Default settings, thus unit is not
operating according to the dip switch
positions observed.
1) Reset this Load Group for Mode 2:
IGN with Timeout & verify time period
selected, see Section V.
2) Check for low voltage at the
battery terminals. If voltage is low:
recharge. If problems persists check
for faulty alternator or replace battery.
3) Re-program the unit - see page 6.

too long resulting in excessive voltage
drop
3) Unit may have been reset to Factory
Default settings, thus unit is not
operating according to the dip switch
positions observed.
1) See Table 6 for LVD disconnect
voltage choices
2) See Table 1 ‘Recommended input
power feed wire size’ and increase
wire size or reduce wire length.
3) Re-program the unit - see page 6.
