Notes for Safety Barriers:
1. Terminal numbers shown are for MTL Barriers.
2. Barriers should be earthed by a 4 sq. mm (minimum) wire .
Notes for field wiring:
1. Refer to drawing DWGV 220 001 2 for additional information.
2. Field cable should have 3 untwisted stranded wires.
3. Capacitance between each two wires: 200 pF/m maximum.
4. Inductance of each wire: 0.7 uH/m maximum.
5. Cable insulation should withstand an AC test voltage
of 500 V R.M.S. to earth or to apparatus frame for one minute.
3. Safety Barriers are installed in Safe Area.
4. Refer to drawing DWGV 220 001 2 for additional information.
1. The Board is configured to 110VAC OR 220VAC by soldered jumpers.
2. R2 (10K trimmer) may be installed off board next to Air / High Oil Light on front panel.
3. R5 (10K trimmer) may be installed off board next to Water Light on front panel.
4. Alternatively, R2 and R5 may be installed on board.
Notes for Main Board:
Note on internal wiring:
The wire from TB1-4 is not usually connected. It may be used for
backward compatibility with systems that used to
indicate failure by de-energizing relay RY2.
