"Level-triggered": activation by negative signal edge, deactivation by positive signal edge. Active at signal level "Low".
Table 6- 20 Function assignment at function (pre-selection): "Calibration"
Function
Trigger
Remark / effect
Calibration 01 to 36
Positive edge
1)
Calibration 01 to 36
Start single calibration. The calibrations must be assigned in the calibration
pool.
Control calibration
Positive edge
1)
Control of a calibration started via a digital input (Calibration 01 to 36) / start
of the next calibration:
This causes the switch to the next intermediate steps during calibration.
Execution of the next step in the sequence is then time related.
• Time 1 after the start of a calibration:
There is calibration gas in the device, the calculation is being made, the
signal filter is active.
• Time 2:
– 1-point calibration is completed (zero gas or span gas calibration)
– 2-point calibration: Injection of span gas necessary
• Time 3 (only with 2-point calibration):
There is calibration gas in the device, the calculation is being made, the
signal filter is active.
• Time 4:
2-point calibration is completed.
1)
"Edge triggered": Activation by rising signal edge.
