One of my modules doesn't seem to be releasing pressure as set by the "Global Release" setting. What should I do?

Refer to RF Service Procedure Module Testing (RFS001).

First, check the pressure within the module. If the pressure is approaching 10 psi, stop using this module and unscrew the module top immediately to avoid over-pressurizing the bottle.

If the bottle is at a safe pressure (<10 psi), confirm that the "Global Release" Set button has been clicked. If a number is only typed in the "Global Release" box and the "Set" button has not been clicked, your desired global release setting will not be populated into the "Pressure Release" fields below each module # column. In this case, valves will not open to release pressure to your desired setting. Click "Set" if needed.

It may be that the exhaust tube is stuck from either lack of use or from condensation of the content that was in the bottle. While twisting back and forth the exhaust tube, gently pull on the tube to see if it is stuck shut. If this causes pressure to release, then execute the vent valve cleaning procedure detailed in RF Service Procedure Vent Valve Cleaning (RFS006) listed in the documents below. 

Also, be sure the battery is not in the yellow range (6.29-6.00 volts) or red zone (<6.00 volts). It is possible that in the lower end of the yellow and in the red voltage range the battery will have enough power to communicate but not enough to open the valve; change the battery.

If this does not solve the problem, listen for the solenoid faintly clicking (this will occur once every 15 seconds as the solenoid opens the valve). If it is clicking, but no pressure is releasing then the valve is stuck closed. Remove the module from the test and contact ANKOM Technology at www.ankom.com/contact/technical-services or call (315) 986-8090 for module repair.

If no clicking sound is audible, the solenoid may have been partially unplugged from the circuit board. The solenoid has two thin white wires going to a small white 2-pin connector on the circuit board. Make sure the connector is securely plugged in and that the wires are not loose. If this does not resolve the problem, there may be a problem with the circuit board or the solenoid. Remove the module from the test and contact ANKOM Technology for module repair.
