All LEDs on the Remote I/O Heador
Remote Drive Interface Headare Off
Problem: All LEDs on the Remote I/O Head (or Remote Drive
Interface Head) are off. This problem indicates that the Head is not
receiving 120 VAC (or 240 VAC) power within the specified ranges,
the fuse has blown, or that the Head is malfunctioning.
DANGER
THE FOLLOWING STEPS ARE PERFORMED WITH POWER ON. EXERCISE
EXTREME CAUTION BECAUSE HAZARDOUS VOLTAGE EXISTS. FAILURE TO
OBSERVE THIS PRECAUTION COULD RESULT IN SEVERE BODILY INJURY OR
LOSS OF LIFE.
Step 1.
Using a voltmeter, verify that the power source is 120 VAC
or 240 VAC, whichever is appropriate, and that it is
functioning correctly. Verify that the jumper on the terminal
strip is set correctly.
Step 2.
Stop any application programs that may be running.
Step 3.
Turn off power to the Remote I/O Head (or Remote Drive
Interface Head).
Step 4.
Inspect the Head fuse using the directions below. If the
fuse is blown, replace it.
CAUTION:
The fuse must be replaced only with another fuse of the exact same type, an
AGC 2 amp fuse. Failure to observe this precaution could result in damage to, or
destruction of, the equipment.
a.) Using a screwdriver, press down and turn
counterclockwise to release the fuseholder located on
the faceplate.
b.) Pull the fuseholder out of the Head.
c.) Remove the old fuse from the fuseholder and replace
it with the new fuse.
d.) ReĆinsert the fuseholder into the Head.
e.) Press down and turn the screwdriver clockwise to
reinstall the fuseholder. The fuseholder must be flush
against the faceplate.
Step 5.
Turn on power to the Head. If the LEDs on the Head do
not turn on, replace the Head.
