DANGER
VOLTAGE IS PRESENT ON THE PLUG CONNECTOR TERMINALS. DISCONNECT
THE POWER AT THE SOURCE BEFORE TOUCHING THE PLUG CONNECTOR
TERMINALS. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN
SEVERE BODILYINJURYOR LOSS OF LIFE.
DANGER
DO NOT TOUCH THE CONNECTORS ON THE FACEPLATE IF THERE IS POWER
ON THE WIRES ATTACHED TO THE PLUG CONNECTOR SCREW TERMINALS.
ALWAYS TURN OFF POWER BEFORE HANDLING A CONNECTOR THAT IS
WIRED. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN SEVERE
BODILYINJURYOR LOSS OF LIFE.
Step 2. Turn off power to the module. Verify that the input power
connector is connected securely to the faceplate. Verify
that the I/O Rail cable connections are tight at both ends.
Step 3. Turn on power to the module. If LEDs are still off, try
replacingthe I/O Rail cable. Check that the pins on the
input connector are not bent.
Step 4. If the LEDs are still off, turn off power to the module and
replace the power supply fuse on the front panel
followingthe directions below.
CAUTION
MAKE CERTAIN THAT THE ANALOG RAIL MODULE CONTAINS THE PROPER
FUSE FOR THE POWER SUPPLYBEING USED. USE A .25 A FUSE FOR 120 VAC
POWER AND A .75A FUSE FOR 24 VDC POWER. FAILURE TO OBSERVE THIS
PRECAUTION COULD RESULT IN DAMAGE TO OR DESTRUCTION OF THE
EQUIPMENT.
a) Use a screwdriver to release the fuse holder located
on the AnalogRail module faceplate. Pull the fuse
holder out of the module.
b) Take the old fuse out of the fuse holder and replace it
with the new fuse. Use a .25A fuse for 120 VAC power
and a .75A fuse for 24 VDC power. See Appendix A for
the fuse type and rating.
c) ReĆinsert the fuse holder into the module. Turn the
screwdriver clockwise while pressingdown on the
fuse holder. The fuse holder must be flush against the
faceplate.
Step 5. Turn on power to the module. If both LEDs still do not
light, replace the module.
