Connect Power
8. The control box can be powered by 230 VAC, 110
VAC, or 24 VDC.
AC power is connected to J6 on the circuit board.
The ground connection is the pin between the pins
N and 110. See F
a. To operate on 230 VAC, connect between pins
marked N and 220.
b. To operate from 110 VAC, connect between
pins marked N and 110.
c. To operate from 24 VDC, connect to J1. J1 is
marked for positive and negative polarity. Dis-
connect any power to the AC connector J6 if the
system is to be powered by 24 VDC. See F
9. Connect an external ACPRH, air valve, etc. to the
internal relay (CRS), if desired, using J4. See F
•
C (Common)
•
R is Reset, which is connected to Common
during normal operation. (NO)

an error is detected. (NC)
10. Reinstall the cover (D) using the four screws (C).
Grounding
1. Follow the instructions in your pump manual to
ground the Graco diaphragm pump system and
check its electrical grounding continuity.
2. When the Leak Detector is powered by 230 VAC or
110 VAC, ground the Leak Detector by connecting
the ground wire to terminal G on terminal J6. See
F
Connect the leak detector to a 24 VDC power source
OR a 110 VAC or 230 VAC power source. Do not
connect to both.
