Corrective Action
C.
Check power on the connector of the
problem actuator while trying to
manually open or close an actuator.
Pins 1 (Black) and 4 (White) should
read +24VDC when the actuator is
opening. Pins 2 (Red) and 4 (White)
should measure -24VDC when the
actuator is closing). If either voltage is
missing, the AIF board is likely bad.
Test the actuator by plugging into
another connector.
operates, replace the board.
D.
Check resistance of the potentiometer
between pin 3 (blue wire) and pin 4
(gray/white wire). Closed should read
0-560Ω. Open should read 3.8K Ω –
6.6K Ω.
E.
If proper voltages are present at the
connector and actuator doesn't operate
reset power to the fryer, if it still
doesn't operate replace the actuator.
A.
Ensure the actuator is plugged into
correct connection (J1 for FV return,
J3 for DV return and J6 for FV drain
and J7 for DV drain).
B.
Ensure the locator pin is in proper
position in plug J2. See table B on
page 1-65.
