Page 22: Control Pushbuttons
6.1.2 Control Pushbuttons Through the key marked CH you can select a measurement channel. This is necessary, for example, when wanting to switch a certain sensor on or off, or when wanting to change the sensor parameters. The symbol Para for the selected measurement channel flashes for 10 seconds. -
Page 23: Operating Modes
Operating Modes The multichannel gauge may be operated in one of the following operating modes: Measurement Mode The measurement mode is the standard operating mode. Here the measured values or status messages are displayed. Chapter 6.4 Measurement Mode, page 23 Parameter Mode In the parameter mode you have access to different parameters. -

Page 26: Parameter Mode
Parameter Mode 6.5.1 Selection By operating the PARA pushbutton for approximately 2 seconds the instrument changes from the measurement mode to the parameter mode. The Para indicator comes on for the channel selected in each case. When the instrument is running in the parameter mode and if no pushbutton is operated for 10 seconds, then the instrument will automatically return back to the measurement mode. -

6.5.3 Operating Concept From the measurement mode, you can select and change a certain parameter as follows: Press the pushbutton CH, so as to select the desired measurement channel (only necessary when wanting to change a sensor parameter) The Para status indicator flashes for the selected channel. ... -
Page 28: Parameters
Basic Terms Switching functions The DISPLAY TWO contains four relays with change-over contacts, from which two for switching functions and two are available as ready function. The relays for the ready functions can be used alternatively also for switching functions. -
Page 29: Configuring The Switching Functions
Figure 18 – Behaviour of a switching function in response to pressure changes Pressure Time Normally open contact COM Common contact Normally closed contact The range between the lower and the upper threshold value produces a certain amount of hysteresis between switching on and switching off of the relay. The hysterisis prevents rapid switching on and off of the switching function when the pressure is close to a switching threshold. -
Page 30: Sensor Parameters (Para Sen)

CH 2 Through measurement channel 2. With the aid of the next parameter t-on you can define a switch-on threshold. As soon as the pressure in measurement channel 2 drops below the switch-on threshold, the sensor will be switched on. CH 3 Through measurement channel 3. -
Page 33: Sensor Switch-Off Value (T-Off)
7.2.8 Sensor Switch-off Value (t-off) This parameter will only appear when the sensor switch-off type has been set to CH 1, CH 2 or CH 3 ( Chapter 7.2.7 Sensor Switch-off type (S-oFF), page 32). Through the parameter t-off you can define a switch-off value. If the pressure in the respective measurement channel exceeds the switch-off value, the PENNINGVAC sensors PTR81N, PTR225, PTR225N, PTR225S, PTR225SN, PTR237 and PTR237N are switched off. -
