3.5 Instrument multiplexer related error messages

E 28
The hose ID measurement signal is out of bounds. If this error only occurs with one instru-
ment; check the condition or corrosion of the quick connector pins. Replace the hose. Check
visually the IMUX for any water leakage or corrosion on the PCB. Replace the IMUX if neces-
sary.

E 29
The fibre-light voltage regulator is not able to regulate the voltage to the fibre-light bulbs. Dur-
ing this error the instruments containing a fibre-light (turbines, micromotors and syringes) are
not activated, to save the bulb from destruction. If this problem only occurs with one instru-
ment then try first to replace the hose for this before replacing the whole IMUX.

E 32.n Error in serial communication between MCB and IMUX
The communication between the MCB and IMUX is serial to reduce the number of wires to a
minimum between these two. The MCB generates this error if there is any reason why it can-
not communicate with the IMUX. Here are the reasons and remedies;
E 32.1
Check the two LEDs on the IMUX. If both are dark, check the cable at both ends. Disconnect
the cable from both ends and measure all wires for shorts or opens. The green LED indicates
(on IMUX) that the IMUX gets power from MCB. The yellow LED (when blinking) shows that
the IMUX CPU is running and communicating with the MCB. Try with an external cable out-
side the arm, or try to connect temporarily another IMUX externally to check what is causing
the problem.
E 32.2
A new IMUX has just recently been installed that has some new features that the MCB soft-
ware cannot use. Please upgrade the MCB software. After the upgrade the MCB is still com-
patible with older versions of the IMUX as well.
E 32.3
Check the pin 6 in P3 on the MCB that it is not shorted to the chassis. Try with another IMUX.
This line is short circuit proof and cannot be harmed even if shorted to ground.
E 32.4
The communication between the MCB and IMUX seems to work most of the time, but there
can be an intermittent contact problem in the IMUX cable. Check the connectors and the pins.

D-14 Planmeca Compact i
Error in hose identification system in IMUX
Reference resistor signal out of bounds when unit is switched on
Active instrument signal out of bounds
Syringe signal out of bounds
Reference resistor signal out of bounds when instrument is activated
Syrine signal changes during use (blinking)
Voltage error in the fibre-light power supply in the IMUX
IMUX is not responding. IMUX cable disconnected or failure in cable or IMUX.
IMUX software is not compatible (IMUX is of new type), with the MCB software.
IMUX data error (cable short circuit) (data low all the time)
IMUX communication error (checksum or parity) (1 sec timeout)
Wrong IMUX type or wrong unit type, see service mode 100 and 103.
