Operating time :
Settings accessible in maintenance level
1. T1: Pulse time on an declogging solenoid valve.
Adjustable from 30 to 2550 ms. Note: setting rounded to within 10ms.
Or, depending on configuration, setting from 3 to 255 1 / 100th of a second
2. T2: Main pause time between 2 declogging solenoid valve pulses.
Adjustable from 1 to 255 sec.
3. T2A: Secondary pause time between 2 declogging solenoid valve pulses.
Adjustable from 1 to 255 sec.
4. Manual forcing of the pause time between 2 declogging solenoid valve pulses in T2A.
Press the "YES" button to use T2A instead of T2.
To cancel the forcing, press the button marked "Forcing OK" again
Forcing authorized at manufacturer level
Note: The order to operate with a T2A pause time rather than T2 can be given by the DCS via the COM or
by manual forcing via the HMI. The last setting made takes priority.
5. T8: Time for checking the minimum pressure in the compressed air tanks (see fault check
→
mini pressure
fault).
Adjustable from 0 to 255 sec
Note: if set to 0: no mini pressure check
6. T9: Time for checking the re-inflation of the compressed air tanks (see fault check
→
re-inflation tank fault).
Adjustable from 0 to 255 sec.
Note: if set to 0: no re-inflation tank check, no compressed air consumption check.
