DP.3 Check the Operation of the Power Relay or Thermostats
The pre‐conditions for this diagnostic procedure are as follows:
The heater LED is illuminated.
Indicator DS2 on the main board is
not
illuminated.
Indicators DS5 and DS6 on all hose/gun modules are
not
illuminated.
1. De‐energize the melter. Refer to Section 1,
Safety
.
2. Remove all of the hose/gun modules.
3. Re‐energize the melter.
NOTE:
If an F1 fault re‐occurs after re‐energizing the melter, reset the
melter and turn the heaters back on.
4. Press the
Heaters
key.
See Figure 6‐1.
5. Check indicator DS2 on the main board, and then do
one
of the following:
If indicator DS2
does
illuminate, go to step 6.
If indicator DS2 does
not
illuminate, got to step 7.
6. Locate a failed hose/gun module by
individually
replacing and checking
each module as follows:
a. De‐energize the melter.
b. Replace the hose/gun module.
c. Re‐energize the melter.
d. Check if LED DS5 illuminates.
Replace the hose/gun module that causes LED DS5
not
to illuminate
when the melter is re‐energized.
7. Complete
one
or
both
of the following checks to determine if the main
board or a thermostat has failed:
a. Check for 21–27 VDC across receptacle J9, pins 1 and 6. If the
voltage is
incorrect
, replace the main board, otherwise go to b.
b. Check for 21–27 VDC across receptacle J9, pins 2 and 6. If the
voltage is
incorrect
, one or both of the thermostats or the wire harness
connected to receptacle J7 has failed. Refer to
DP.6 Check the
Resistance of the Tank/Manifold Thermostat
. If the voltage is
correct
,
replace the main board.
