1.2.1.4 Automatic restart after voltage failure
For compressors leaving the factory, this function is made
inactive. If desired, the function can be activated. Consult
Atlas Copco.
Warning
If activated and provided the regulator was in the automatic
operation mode and the compressor control mode (local, remote
1 or remote 2 - see section 1.2.3) was not changed during the
voltage failure, the compressor will automatically restart if the
supply voltage to the module is restored within a programmed
time period (this time period is called the power recovery
time).
The power recovery time can be set between 1 and 254 seconds
or to 0. If the power recovery time is set to 0, the compressor
will always restart after a voltage failure, no matter how long it
takes to restore the voltage.
1.2.1.5 Permissive start
After a start command (either automatic start by the electronic
regulator or manual start), the permissive start function is
operating: if the oil injection pressure at the compressor
elements exceeds the programmed level, the compressor will
not start (indicated as <<Start failure>>). See "User manual
for Elektronikon regulator", section "Programmable settings
for GA90/315".
