1.2 Connections
The rear of the meter may have up to three terminal strips. The main 14 terminal strip (J1) is the
standard. If options are present then two shorter terminal strips (J2 & J3) will be present and
physically located above J1.
J1 (CHS1000, CHS1100, and CHS1200)
1 - VAC Hot / DC+ 6 - Pump Relay # 1 11 - +24VDC @ 100mA
2 - VAC Neutral / DC- 7 – Alarm Relay #1 12 – SIGNAL I/P s)
3 – Ground 8 – Alarm Relay #1 13 - SIGNAL I/P sinking (-)
4 – Common 9 – Alarm Relay #2 14 – Common
5 – Pump Relay #1 10 – Alarm Relay #2 SEE NOTES BELOW RE: Inputs
J2 (CHS1100 and CHS1200 only)
1 - Common (Pulse return) 5 – Float/HOA switch I/P Disable #2
2 – RUN / Pulse I/P# 2 (5-50VDC) 6 – Float/HOA switch I/P Disable #1
3 – RUN / Pulse I/P#1 (5-50VDC) 7 – Re-transmitted level 4-20mA (-)
4 – Common (HOA return) 8 – Re-transmitted level 4-20mA (+)
J3 (CHS1200 only)
1 – RS-485 (-) 5 – RS-232 RTS (see Note 2)
2 – RS-485 (+) 6 – RS-232 TX data
3 – SIG common 7 – RS-232 RX data
4 – RS-232 RTS (see Note 2)
NOTES:
All relays Form A rated 5A @ 120 VAC
Use Terminals 12 (+) and 13 (-) for sinking inputs (i.e. 2 wire transmitters)
Use terminals 13(+) and 14(-) for sourcing inputs (i.e. 4 wire transmitters)
For RS-485 or for quick turn-around RS-232, jumper RTS and CTS.
For external modem use, connect RTS and CTS to the modem. The modem provides the CTS
delays as needed.
