Introduction:
The picture shows the rear panel of the ipm600 meter. The left part of the panel is where the power supply is connected. F.G. stands for the ‘frame ground’, this is a ground terminal block. Be sure to ground the F.G. terminal to prevent electric shocks and failures due to static electricity. The AC power supply should be between 100 and 220V and the frequency is 50/60 Hz.

Setup:
The sensor that will drive this meter will be connected through pins, A1, A2, B1 and B2. The excitation wires from the sensor will connect to the A pins while the signal wires will connect to the B pins. The descriptions of the other pins are below. If you have a six-wire sensor then jump the ‘sense’ wires with the excitation wires as shown.

Input/Output Connections:
A3 (COM1):
The terminal common to output signals

When the HI limit is reached this HI output is turned on
A5 (HH):
When the HI HI limit is reached this HI HI output is turned on
A6 (COM2):
The terminal common to input signals
A7 (CODE0):
Selects the CH No. for HI-Lo limit comparison in combination with A8, B7 and B8
A8 (CODE2):
Selects the CH No. for HI-Lo limit comparison in combination with A7, B7 and B8
A9 (T/H):

B3 (OK):
Outputs the OK signal
B4 (LO):
When the LO limit is reached this LO output is turned on
B5 (LL):
When the LO LO limit is reached this LO LO output is turned on
B6 (H/E):
Outputs the hold-end signal
B7 (CODE1):
Selects the CH No. for HI-Lo limit comparison in combination with A7, A8 and B8
