Check clock pulse air dryer change-over
Deadly risk!
Working on open, live equipment!
• Do not operate the equipment with damp hands!
• Caution: live components!
Risk of injury!
Wear protective goggles when opening safety valve „high pressure” (29)!
Setpoint value
The clock pulse of the air dryer change-over is system-dependent factory preset in the MFR (
45
):
• 60 s ± 10 %
Check clock pulse
• Switch on operating voltage.
• Open safety valve "high pressure" (
29
).
•
The compressor (
8
) must run.
• Measure clock pulse.
The MFR (
45
) controls the solenoid valves (
36
) of the air
dryer in the clock pulse regarding the compressor run time.
The change of the valves is visualised by the LEDs „Y1-
State“ (
54
) and „Y2-State“ (
55
) on the MFR and the LEDs at
the solenoid valves (
36
). It is also audible by the sudden
escape of regeneration air into the condensate surge hose
(
10
).

Set clock pulse
• The clock pulse is factory preset and can be altered by the manufacturer only.
Compressor runtime surveillance
Deadly risk!
Working on open, live equipment!
• Do not operate the equipment with damp hands!
• Caution: live components!
Setpoint value
The maximum admissible compressor runtime is factory preset according to the equipment’s needs and stored
in the MFR (
45
):
RTS 1000:
0 sec
Set runtime period
• The admissible runtime period is factory preset and can be altered by the manufacturer only
