9.1 Heater Circuit Test
9.1.1 Startup
On startup, the H cards do a heater circuit test on all zones before full power is applied. This
is to minimize risk of damage to the controller or hot runner system. The time for this test is
18 seconds and is done before the Soft Start is started. Refer to Section 9.3 for information on
the Soft Start.
This heater circuit test is very important in that it detects the heater circuit faults that follow:
WARNING!
Please read this entire manual before you start the system. Call the nearest Husky
Regional Service and Sales office with any questions.
Faults Description
Open Circuit Occurs when a conductor is broken or becomes loose and no current
flows through its related circuit.
Short Circuit Occurs when current flows through an incorrect circuit or directly to
ground as the result of a wiring error across the heater outputs, a pair of
frayed conductors, or a crimped wire.
Leakage A low current short to ground that usually occurs when moisture is
absorbed by a heater’s insulation material.
Wrong Heater When the heater would apply more than the heat capacity of the zone it
is connected to in the controller.
