B) Check K3 and K6 relays (located in safety enclosure) to be sure they
are operational. If not, check interlock switches (located on pedestal
doors) to be sure they are engaged. (Ref: Power Control Schematic
in Documentation Section.)
C) Check K4 relay (located on OPTO22 panel. (Ref: Channel
Assignment Sheet) Check for illuminated LED, indicating an active
output.
NOTE: K4 has diagnostic circuitry by allowing the user to
manually control the status of the output.

4.2.2.2.The heat is in a runaway condition and cannot be shut off by
changing the setpoint to a lower value.
A) The SCR needs calibration. See “Maint” screen for details. (Ref:
Engineering Specification 00028 in Documentation Section)
B) The SCR has failed and shorted. Replace SCR.
4.2.2.3.Zone temperature fluctuates.
A) The SCR needs calibration
B) Improper flowmeter setting(s)
C) Adjacent zone temperature differentials are too large
D) Improper PID setting(s)
NOTE: The following are factory typical settings:

4.2.3. Conveyor System
4.2.3.1.A Transport Speed Error occurred.
A) Check fuse “FB” (located in safety enclosure box). (Ref: Power
Control Schematic in Documentation Control Section)
B) Check fuses “F1” and “F2” on Motor Speed Control PCB (located in
the motor box). (Ref: Frame Wiring Schematic in Documentation
Control Section)
C) Inspect clutch for slippage. (Ref: Section 3.1.3.15)
D) Visually inspect for belt jam or snag.
