After setting a parameter, the power supply of the SCTSi must remain stable for at least 3 sec-
onds, otherwise there may be a loss of data.
Access to the SCTSi parameters via NFC also works when the supply voltage is not connected.
6.4 Ejector SCPSt Functions
Functions of the ejectors SCPSt:
•
Switching points for control and component checks
•
Air saving functions
•
Blow-off functions
•
Setting for the permitted evacuation time t1
•
Setting for the permitted leakage
•
Permanent and erasable counters for the suction cycles and switching frequency of the valves
•
Manual operation
•
Ejector control (suction and release)
•
Display of the ejector status (status of the vacuum level)
The functions relate to an ejector Compact terminal SCTSi and apply to each individual ejector, regardless
of the number of installed ejectors discs.
6.4.1 Switching Points (0x0064 to 0x0067)
Two separate switching points can be set for the ejector. Each switching point has an activation point and
a corresponding hysteresis. The system vacuum is constantly compared to the set values for the switching
points during operation.
An LED displays when the switching point for H2 is reached.
The set values for H2 must be lower than the values for H1. The exact configuration conditions can be
found in the parameter descriptions.
