Heater Circuit Test
9.1.1 Startup
On startup, H cards perform a heater circuit test on all zones before full power is applied, to
minimize risk of damage to the controller or hot runner system. The duration of this test is 15
seconds and is carried out before the soft start routine is activated.
This test is critical for detecting the following heater circuit faults:
Open Circuit
Short Circuit
Leakage
Wrong Heater

Faults
Occurs when a conductor is broken or comes loose and no current flows
through the circuit it is associated with.
Occurs when current travels along an unintended path as the result of a
wiring error across the heater outputs, a pair of frayed conductors or a
pinched wire.
A low current short to ground that typically occurs when moisture is
absorbed by a heater's insulation material.
This is a case when the heater exceeds the capacity of the zone it is
connected to in the controller.
