Pressurized reservoir with air regulator ValveMate 7140 Controller Caution: Always depressurize the reservoir before opening. To do this, slide the shutoff valve on the air line away from the reservoir. If using an EFD tank, open the pressure relief valve as well. Before opening the reservoir, check the pressure gauge to verify that pressure is zero (0).
Mounting the ValveMate 7140 The ValveMate 7140 can be mounted either over or under a surface using screws to secure bracket. Use the universal mounting bracket (included) to mount the controller either over or under the cabinet. The bracket allows the controller to pivot 30º from a horizontal position.
External Power Adapter A universal 24VDC remote power supply with a locking ring DC connector is included with each ValveMate 7140. Select a convenient location and connect to appropriate input voltage. Back Panel Markings Maximum Air Pressure Caution Caution symbol informing that the maximum air input pressure is 100 psi (6.9 bar).
Input/Output Connections The 10 pin terminal strip includes a 5-24VDC and contact closure CC initiate inputs. Outputs include an Alarm Out, End of Cycle EOC and a 24VDC courtesy power. 5-24 INIT: Dispense initiate input activated with a 5-24VDC input voltage. EOC OUT: End-of-cycle feedback ALARM OUT: Circuit that closes when an alarm condition is present.

PLC input. Maximum load is 100mA, 5-24 VDC. Alarm IN Connection The ValveMate 7140 offers an alternate use of the CC INIT initiate input for an external alarm signal. Refer to the ʻHow toʼ instructions on page 15 to enable.
Air Connections Air Input Connection Connect the ValveMate 7140 to plant air by first installing the EFD five-micron filter regulator (#7002002) included to your air supply. Install the air tee with 6mm push-in fitting (#7016230) in the output of the filter regulator. Connect 3 meter length of 6mm tubing into push-in fitting.
Final Setup Checklist 1. Air pressure to ValveMate 7140 is set to 70 psi (4.9 bar). 2. Nozzle air pressure regulator is set to 10 psi (0.7 bar). 3. Initiate connection and I/O are wired correctly. 4. Spray valve and fluid reservoir are properly connected.
Testing the Spray Valve 1. Set tank pressure. For low viscosity, low pressures and high viscosity, higher pressure. 2. Using the Mode button on the ValveMate controller, place the controller in the PURGE mode. In PURGE mode, Actuating Air can be selected independently of Nozzle Air by following “How to purge with or without nozzle air”...
If problem persists, make sure devices such as air cylinders are not causing a pressure drop in the ValveMate 7140 input air line. Check to make sure the unit is not in a mode other than RUN. Response delay in...
