4.6.5 Sensor configuration
Basic sensor configuration must be adapted according to application needs.
• ZERO function: This may be ‘disabled’ or ‘enabled’. Default is ‘enabled‘. Refer also to chapter
«ZERO».
• Sensor configuration with 2 sensor version [612 . . - . . . X - . . . .]. Refer also to chapter: «Pressure
control operation with 2 sensors».
Local operation:
(‘Control Performance Analyzer’ or ‘Service Box 2‘)
Remote operation:
With CPA:
• Do sensor configuration in menu ‘Sensor /
Setup’.
With SB2:
• Enable or disable ZERO function in menu
‘Setup / Sensor’.
• Do 2 sensor configuration in menu ‘Setup
/ Sensor’.
1. Go to «EtherCAT object – Index 20E6h» >
«SENSOR OPERATION MODE» and set
valid value:
0 = no sensor
1 = 1 sensor operation (sensor 1 input)
2 = 2 sensor operation with automatic
changeover (low range = sensor 2 input, high
range = sensor 1 input)
3 = 1 sensor operation (sensor 2 input)
4 = 2 sensor operation with automatic
changeover (low range = sensor 1 input, high
range = sensor 2 input)
Note: Sensor operation modes 2, 3 and 4 are
possible with 2 sensor hardware(612 . . - . . .
H - . . . . and 612 . . - . . . W - . . . .) only.
This function does the sensor configuration
for pressure control.
2. Go to «EtherCAT object – Index 20E7h» >
«SENSOR FULL SCALE RATIO» and set
valid value
Value is calculated as follows.
High range sensor full scale value / Low
range sensor full scale value. See picture
«Pressure / High range, Low range sensor»
below.
Picture below shows a 2 sensor system. In
this configuration sensor 2 covers low range
(100 mTorr) and sensor 1 covers high range
(1 Torr).
This example results to an “Sensor full scale
value” of 10.0 (1Torr / 100mTorr).
