43 Motor protective switch [Q4]
to manually switch the compressors on and off, features a built-in protective relay to protect the motor
from excessive current consumption.
44 Motor contactor [K1]
switches the compressor (
8
) [2.1] on and off after the switching of the pressure monitor (
40
) [F6]
.
45 Multifunctional relay MFR
controls all workflows of the pressurisation equipment, among others:
- redirects the solenoid valves (
36
) [Y1 and Y2] to change the drying agent container in the clock pulse.
-
switches off the compressor via the motor contactor (
44
) [K1] and activates the signal "F" when the
humidity content of the dried air is inadmissibly high.
-
activates the output common signal "A" (fault) in potential free form, when the faults "F" is pending, or if
the systems AC power broke down. The individual signals of the output common signal are dependent
on equipment.
46 Signal relay „A” [K11]
switches in case of exceeding the alarmthresholds of „A” (local common alarm)
.
26 Power pack 24 V DC [G1]
supplies 24 V direct current for control elements and indicators
.
