Liquid Controls LCRII Install E3650-E3651 Series - Manual (Page 37)

Wiring Tables
This appendix provides a tabular description of the wiring connections made to each LCR-II terminal block. It should
be referenced in the event wiring is inadvertently mis-routed in the field, or for general troubleshooting in the event of
a problem.
Pull-down resistors of 300 Ω needs to be connected between
CHAN B and GND, and CHAN A and GND.
To operate a single channel pulser, a jumper is required between
pins 2 and 3 on J4.
