no problem is found, replace the sensor.
Check the sensor for an installation problem and the actuator for
a bending or operation error.
If no problem is found, replace the sensor.
Switch (Normal Open) fault FIP
Enter Chain XX Func XXX in Diag (CE) mode. Turn on the
switch.
Does the display change to LOW?
Y
N
Is the v5 VDC between the swith pin 2 (+) and
GND(-)?
Y
N
Check between the Switch pin 2 and PWB pin 3 for an
open wire or poor contact. If no problem is found,
replace the PWB.
When the switch is on, is the v5 VDC between the
Switch pin 1(+) and GND?
Y
N
Replace the switch.
Check between the PWB pin 4 and switch pin 1 for an open
wire or poor contact. If no problem is found, replace the
PWB.
Turn off the switch. Does the display change to HIGH?
Y
N
Disconnect the switch connector.
Is the display still HIGH?
Y
N
