8.2.1 Zone Cooling Time
On some molds, it may be necessary to wait before moving on to test the next zone. This time
is needed in cases where, after the power has been removed, the thermocouple continues to
heat longer than expected. This is common with large manifolds. If Neo5 started testing the
next zone before the previous zone's temperature stopped increasing, this could affect the
test results. The default setting is 10 seconds. Each mold setup can have its own set of cooling
times.
8.2.2 Maximum Test Time
On some molds, if there is a thermocouple wiring problem, a heater could be damaged
during test. Specifically, some heaters in some configurations may not support the peak
temperatures reached when full power is applied for the default test time. An extreme
example is testing a hot runner without the cavity plate in position. If the heater is large, a
short test time may not be long enough to heat up and result in a failed test. Operators can
set the maximum test time for each zone to accommodate different types of heaters. The
default setting is 2 minutes. Each mold setup can have its own set of maximum test times.
8.2.3 Test Definitions
Test Heaters Test — During heating, the maximum current and voltage are recorded and the
resistance is calculated. Also checks for blown fuses.
Test Sensor Test — Tests the correct functioning of the thermocouple. For example, if a
thermocouple is lost or reversed.
Test Wiring Test — Makes sure that the thermocouple and heaters are paired correctly (1 to
1, 2 to 2, etc). During heating the maximum current and voltage are recorded and the
resistance is calculated. Before the cross talk test is done, the test waits for the zone
temperature to be less than the threshold.
