Fault 4: Pressure release
24-B/24V/30-B/31-B
®
23-S/23V-S/29-S/29V-S
FAULT 4: Pressure release
Triggered by : The monitoring time limit Uet5 for the pressure release until reaching P11 has been exceeded.
Causes/ Remedy
Operating fault /Check by personnel:
• Check that the cooling water outlet pipe is free of kinks and has a steady downward gradient
• Check that the water outflow plumbing in the room is not blocked
Appliance fault / Repair by technical service personnel
► Pressure release solenoid valve does not open
• Electrical control system is faulty
- in the "Diagnosis Program“, switch on output ACOUT 7:
the LED for this output lights up
- Measure voltage at ACOUT 7 of control (approx.230V AC)
- Measure voltage at output of the rectifier socket (approx. 200V DC)
- Check coil of solenoid valve is conducting
• Solenoid valve mechanically blocked (clogging)
Open valve casing
► Pressure release filter clogged
Remove stopper. Check filter sieve for clogging, clean/exchange, insert new seal and screw tight.
► Pressure sensor / Analog input AIN 3 measures too high
Even after pressure release, pressure signal still shows > P11. Follow-on faults would usually be "Fault 1
Vacuum system", " Fault 34: Sterilization TU"
Check the pressure displayed in "Diagnosis Program“/ "Analog inputs“ for plausibility, displayed value
must correspond to current atmospheric pressure (door open)
See also under "Fault 34 Sterilization TU“, "Pressure sensor, Analog input AIN 3 measures too high"
Exchange pressure sensor
If fault occurs again exchange CPU-board

Fault 8: Time base
FAULT 8: TIME BASE
Triggered by:
Maximum difference between the program duration and the internal timer has been exceeded
Causes/ Remedy
Operating fault/Check by personnel:
Appliance fault / Repair by technical service personnel
► Internal hardware fault
• if fault occurs repeatedly, exchange CPU-board

FAULT 9: DOOR OPEN
Triggered by: Door contact (digital input DIN1) was closed during a program
Causes/ Remedy
Operating fault/ Checks by personnel:
• Press down door handle as far as possible
Appliance fault / Repair by technical service personnel
► Door switch faulty
• Door switch faulty / needs readjustment
• Electrical connection to CPU-board interrupted
• Digital input DIN1 on CPU-board faulty
Check in the MELAG- Diagnosis-Program, "Digital Inputs: E 1“
it the door switch needs adjusting, see below.
Adjusting the door contact switch
• In the diagnosis program "Digital Inputs“ select
"Input E1: Door contact“
• Insert 8 mm spacer (M8 bolt or similar) between
lock housing and upper door beam as shown
• Close door and push down door lock until contact is made
• Loosen right fixing screw of door contact switch
• Turn door contact switch around the left fixing
screw until door contact switch engages (Display
shows "closed", switching sound)
• Tighten right adjusting screw in new position
