6.4 Assigning the digital outputs of the I/O module
The available functions can be assigned in any way necessary to the digital outputs
PLC-OUT 1 ... 8 of the I/O module:
STOP
inactive→ active:
Switch to Standby.
(Z
ERO is not possible, all trigger outputs will return "Fail".)
ZERO
inactive→ active:
active→ inactive: Switch Z ERO on.
Switch Z ERO off.
ZERO_PULS inactive→ active. Switch Z ERO on or off.
CLEAR
inactive→ active:
Erase warning or error message / cancel calibration.
GASBALLAST
inactive→ active:
active→ inactive: Open gas ballast valve.
Close gas ballast valve unless always open.
SELECT_DYN_NORMAL
inactive→ active:
active→ inactive:
External calibration mode for the "CAL" function:
External dynamic calibration
(without auto tune, allowing for the measuring times and pump
cycle times set via the digital inputs)
External normal calibration
(with auto tune, not considering the system-specific measuring
times and pump cycle times)
START_STOP
inactive→ active:
active→ inactive:
Switch to Meas.
(Z
ERO is possible, all trigger outputs switch depending on the
leakage rate.)
Switch to Standby.
(Z
ERO is not possible, all trigger outputs will return "Fail".)
KEY_1 active: User "Operator"
KEY_2 active: User "Supervisor"
KEY_3 active: User "Integrator"
CAL inactive→ active:
When set to Standby, the unit will start an internal calibration.
When set to Meas, the unit will start an external calibration.
