Once the gauge has been switched on, it can remain in operation continuously regardless of the pressure. Connect power to the PCM301 using the designated pins 3 and 4 of the 9-pin D-sub connector. Alternatively, you can power the device by connecting InstruTech’s PS401-A power supply to the gauge. 4.2 Gauge Status LEDs... -

<SP2>) is lit solid and the corresponding relay will turn on (energize). The relay will turn off (de-energize) when the pressure drops 10% (hysteresis) below the setpoint. Note that hysteresis can only be changed by using the diagnostic port. InstruTech Page 18... - Page 22 If processes are controlled via the analog output signal, keep in mind that by pushing an <SP> button the measurement signal is suppressed and the corresponding threshold value is output instead. This can cause malfunctions. Push the <SP> button only if you are sure that no malfunction will occur. InstruTech Page 19...

This can cause malfunctions. Push the <SP> button only if you are sure that no malfunction will occur. The atmospheric pressure sensor measures the atmospheric pressure (pressure outside the vacuum system and can be calibrated against the diaphragm capacitive sensor in the gauge.
