Sensor Switch-On Type (Sensor On); Sensor Switch-On Value (T-On) - LEYBOLD GRAPHIX ONE Instruction Manual

7.1.13

Sensor Switch-on Type (Sensor On)

This parameter defines how the sensor is switched on.
You can set the switch-on type to the following values:
Manual
The sensor can be switched on in the channel menu by tapping the button
External
Externally via optocoupler (static signal +12 – +24 VDC)
Hot
Warm start. The sensor is switched on automatically upon switching on the instrument. After
a power failure, the measurement is started automatically.
Channel 1
Through measurement channel 1. With the aid of the then following parameter Sensor
switch-on value you may define a switch-on value. When the pressure in measurement
channel 1 drops below the switch on value, the sensor is switched on.
Channel 2
Through measurement channel 2. With the aid of the then following parameter Sensor
switch-on value you may define a switch-on value. When the pressure in measurement
channel 2 drops below the switch-on value, the sensor is switched on. Selecting
measurement channel 2 is only available for GRAPHIX TWO and THREE.
Channel 3
Through measurement channel 3. With the aid of the then following parameter Sensor
switch-on value you may define a switch-on value. When the pressure in measurement
channel 3 drops below the switch-on value, the sensor is switched on. Measurement
channel 3 is only available for GRAPHIX THREE.
7.1.14

Sensor Switch-on Value (T-On)

This parameter can only be changed provided the sensor switch-on type has been set for
Channel 1, Channel 2 or Channel 3
On), page 72).
With the aid of parameter Sensor switch-on value T-On, you may define a switch-on value
for the sensor. When the pressure in the affected measurement channel drops below the
switch-on value, the sensor is switched on.
