Optional Pneumatic-to-Electric Switch Instructions
Installed on port 4 of the SPILLSTOP's 3-way pneumatic actuator valve ⑥ , the Pneumatic-to-Electric Switch ⑩ is used
to power a warning light or other electrical device when an air operated diaphragm pump has a diaphragm failure and the
SPILLSTOP shuts down the pump (Figure 2). When SPILLSTOP triggers a pump shutdown, the device connected to the
switch will be powered on. When the SPILLSTOP is put back into operation after a pump shutdown, the device will be
powered off.
1. The switch ⑩ has three blade-type electrical contact points:
a. Connect the common, usually white wire of the electrical device to the blade on the top of the switch.
b. Connect the live, usually black wire of the electrical device to the N.C. (Normally Closed) blade connection.
2. Attach the air tube to port 4 of the 3-way pneumatic actuator valve ⑥ and connect to the switch's barb connection.
3. Test the switch before putting the SPILLSTOP into operation:
a. Connect an air line to the SPILLSTOP regulator ① .
b. Adjust the SPILLSTOP regulator ① to a minimum of 40 psi (2.7 bar).
c. Push the float ⑤ up to activate the SPILLSTOP. Air should start flowing through the tube connected to port 4 of the
3-way pneumatic actuator valve ⑥ and the switch should power on the electrical device.
