DETAILED DESCRIPTION OF ERROR MESSAGES
Technical Manual
E 3.n General pressure problem
E 3.1 Incoming air pressure compared to the water pressure is too low
The internal air pressure (after the internal pre-regulator) must always be 100kPa higher than
the internal water pressure (after the internal pre-regulator). Otherwise the membranes in the
IMUX doesn’t close properly. Normally this never causes a problem, except for the cases
when the system compressor is accidentally turned off during the use of the unit. Check that
the incoming pressure is according to specifications. Also measure (and readjust if neces-
sary) the internal pressures of the unit. Use either an external manometer attached to the
syringe, or use the internal service mode system for the check. Check also the condition of
the water and air filters. Look for any kinks in the air tube going to the IMUX.
E 3.2 reserved
E 3.3 reserved
E 3.4 Internal air pressure (after pressure regulator) is too low
E 3.5 Internal air pressure (after pressure regulator) is too high
Check the condition of the input pressures to the unit. Is an external valve or compressor
accidentally closed? Check the water and air filter. Check (and readjust if needed) the internal
pressures.
E 4.n Short circuit in the cable from the MCB to the control panel/
suction holder in branch n
E 4.1 Short circuit in the cable from the MCB to the control panel/suction holder
in branch 1
E 4.2 Short circuit in the cable from the MCB to the control panel/suction holder
in branch 2
The problem must be in the cable, or as the last possibility on the control panel PCB or suc-
tion holder PCB or MCB. Localize the short circuit in the cable, and repair the cable or replace
it. If the error does not disappear, then the control panel PCB or suction holder PCB or MCB
must be replaced.
E 5, 6 reserved
3.2 Power Supply related error messages
E 7 IPS voltage failure on MCB (IPS = Instrument Power Supply)
The IPS output voltage is too high. Disconnect the P3 (cable to the IMUX) on the MCB. If the
error is still there, then the MCB IPS power supply is faulty. Advanced: Check the condition of
Q6, Q9 and Q7 on the MCB.
If the MCB is OK; check the condition of the IMUX (8-wire) cable by disconnecting it both at
the IMUX and MCB. Measure all wires for shorts between each others as well as the chassis.
Replace the cable or the IMUX.
