Test SCR Circuit
1. Test the SCR circuit in the on position:
a. Make sure everything is connected, including
the hose.
b. Turn main power ON .
c. Adjust the hose heat setpoint above the
ambient hose temperature.
d. Turn on heat zone by pressing .
e. Hold down to view electrical current.
Hose current should ramp up to 45A. If there is
no hose current, see E03: No zone current,
page 12. If hose current exceeds 45A, see E02:
High zone current, page 11. If hose current
stays several amps below 45A, hose is too long
or voltage is too low.
2. Test the SCR circuit in the off position:
a. Make sure everything is connected, including
the hose.
b. Turn main power ON .
c. Adjust the hose heat setpoint below the
ambient hose temperature.
d. Turn on heat zone by pressing .
e. Using a voltmeter, carefully measure the
voltage at the hose connector. You should not
get a voltage reading. If you do, the SCR on the
temperature control board is bad. Replace the
temperature control assembly.
Replacing Temperature Control Assembly
Modules
1. Turn main power OFF . Disconnect power
supply.
2. Perform the Pressure Relief Procedure, page 25.
3. Refer to electrical diagrams; see Electrical
Diagrams manual 312067. Temperature control
assembly is on left side inside cabinet.
4. Remove bolts that secure transformer assembly
and slide assembly to side in cabinet.
5. Put on static conductive wrist strap.
6. Disconnect all cables and connectors from
assembly; see Temperature Control, page 66.
7. Remove nuts and take entire temperature control
assembly to workbench.
8. Replace defective module.
9. Install assembly in reverse order.
CAUTION
Before handling assembly, put on a static conductive
wrist strap to protect against static discharge which
can damage assembly. Follow instructions provided
with wrist strap.
