2.
Remove the links from the loop 1 terminals on the terminal board and insert the loop
connections observing the polarity (+ and -).
3.
Power the panel back up.
4.
If the yellow fault light on the terminal board remains on after power up, switch the
panel off and check the loop for continuity (+ to +) and (- to -). Check for a short
circuit between + and -.
5.
If the loop is healthy, i.e. no fault light on the terminal board, wait until the
LOGGING DEVICES message is replaced with the date on the display.
6.
Select List Loop Devices via the keypad. The VFD will then prompt you with LOOP
