Turn the power back on. The Processor Module's display should light
up, and after about a second the Bar Graph display should appear,
followed by the message "AIM COMM FAIL".
5. Connect the Common lead of the voltmeter to TB3 and the power
lead of the voltmeter to the AIM-TB terminal labeled "+5V". The
voltage on the "+5V" terminal should be between +4.75 and +5.25
Vdc.
6. If the voltages are within the limits described above:
A. Turn off the power.
B. Carefully insert the AIM cards back into the AIM Terminal
Block.
C. If you have unplugged the AIM COMM. cable, plug it back in.
D. Press and hold the No key. While pressing it, turn the power
back on. (This procedure is known as a manual controller reset
or No Key reset.)
The green LEDs on the AIM should blink, which means that the
unit is working normally. If they do not blink, contact Watlow-
Anafaze.
E. The MLS-PM will display a "T/C Break" alarm message for
each channel. These messages are normal; to clear them, press
Alarm Ack once for each control loop.
