TRANSFORMER
24 VAC / 50-60 HZ
(SEE NOTES 2 AND 3)
NOTES:
1: CONNECT OUTPUT SIGNAL CABLE DRAINS TO EARTH GROUND AT ONE END OF CABLE ONLY.
2. GF-A2100 AND GF-A2200 ARE NON-ISOLATED DEVICES USING A HALF-WAVE RECTIFIER ON THE 24VAC POWER INPUT. IF MULTIPLE DEVICES ARE POWERED BY THE SAME TRANSFORMER
OUTPUT, ALL GND CONNECTIONS MUST BE COMMON, OR AN ISOLATION TRANSFORMER MAY BE USED TO PREVENT EQUIPMENT DAMAGE.
3. ALL DEVICES ON MULTIPLE GF-A2200/GF-A2200 INSTALLATIONS WITH A COMMON POWER 24VAC SOURCE MUST BE WIRED IN-PHASE TO THE SAME TERMINALS (e.g.: PIN 6 to PIN 6, PIN 7 to PIN 7).
4. SHIELDED TWISTED PAIR (STP) WIRING (SUPPLIED BY OTHERS) IS RECOMMENDED.
5. OUT1 AND OUT2 TYPE CAN EACH BE SELECTED AS
EITHER
AN ANALOG OUTPUT (
TYPE=ALARM
;
FLOW
;
TEMP
;
DIFF FLOW
) OR AS A PID CONTROL OUTPUT (
TYPE=CTRL
) - SEE SETUP MENU DETAIL.
6. DASHED LINES INDICATE ALTERNATE SHIELDED TWISTED PAIR WIRING CONNECTIONS FOR PID CONTROL DEVICES.
