7 Troubleshooting
Problem
Solutions
Tank does not heat
1.
Turn on main power breaker switch. If switch light
fails to illuminate, replace switch.
2.
Inspect power-in connections for proper fit.
3.
Check for faulty wires.
4.
Inspect power wires or power plug at main power
source.
5.
Check supply voltage to melt unit with voltmeter.
The voltage of each component must equal the
supply voltage or system damage will occur.
6.
Check incoming control voltage to terminal blocks.
7.
Check tank controller for proper operation.
8.
Check wire connections against electrical schematic
to ensure melt unit is properly wired.
9.
If problem still exists, replace tank heaters as
specified under Tank Heater Replacement.
Tank heats slowly
1.
Check status of components with a voltmeter
(system powered) or ohmmeter (system unpowered,
wires disconnected).
2.
Adjust tank temperature controller. Inadequate tank
heat can affect performance.
3.
If problem still exists, replace tank heaters as
specified under Tank Heater Replacement.
Tank overtemperature
1.
Check tank temperature when overtemp indicator is
lit. If too high, turn tank controller counterclockwise
to reduce temperature. If light is on at acceptable or
low temperature, switch is faulty or rated at a low
temperature. Replace overtemperature switch.
Applicator and hose heat slowly 1.
Adjust hose and applicator temperature controllers.
Inadequate heat can affect performance.
2.
Verify hose electrical connector is properly
connected.
3.
Check supply voltage to hose controller with volt
meter.
4.
If problem persists, refer to Hose Controller
Replacement.
