Technical Manual
Show console syringe location hose identification signal
(nnn signal)
This service mode shows is similar to the one above. This mode shows the actual signal
measured from the identification pins on the connected hose. The display range is 0 to 255. A
continuous 255 indicates an open circuit, a continuous 0 a short. The signal should be stable
within ± 1 digit.
Show console syringe switch signal (nnn signal)
This service mode shows the (optional) switch signal from the syringe. At this moment no
syringes use this signal, therefore 255 is always shown.
Show IMUX on/off valve signals (¦¦¦¦¦¦ signal)
This service mode shows the actual driver output signals controlling the on/off type electro-
magnetic valves inside the IMUX. The five first vertical segments (counting from right) repre-
sent the four instrument and one syringe select valves, respectively.
The sixth (leftmost) vertical bar shows the (optional) steripump control valve / extra water
valve signal.
A short vertical bar indicates that the valve is off and that the valve is connected properly (not
open circuited). A long vertical bar indicates that either the valve is on or that the valve is
open circuited.
When the SET-mode is entered, IMUX IC16 output signal feedback inputs are displayed:
1st vertical segment (counting from right): Syringe water control
2nd: Instrument 4 membrane control valve
3rd: Instrument 3 membrane control valve
4th: Instrument 2 membrane control valve
5th: Instrument 1 membrane control valve
6th: steripump control valve / extra water valve
7th: Syringe fibre light electronics
8th: Syringe heater
Show IMUX other output signals (¦¦¦¦¦¦ signal)
This service mode is similar to the one above. This mode shows the other outputs driver sta-
tuses controlling the relays and other outputs. This service mode is mainly intended for fac-
tory use.
Show air / water pressure difference
This service mode shows the measured pressure difference between the internal continuous
air pressure and the regulated spray water fed to the instruments. This pressure difference
should always be greater than 1 bar (100kPa) to guarantee proper operation.
Show active instrument drive/cooling air pressure
(n.nn bar; nnn kPa; nn.n PSI pressure)
This service mode shows the signal from the drive/cooling air line pressure sensor. The dis-
play is either in bar, kPa or PSI, depending of the setting in the service mode n.17. The pres-
sure is measured inside the IMUX just after the proportional valve controlling this line.
Therefore this pressure display is (under normal flow conditions) always higher than the pres-
sure measured at the instrument end of the hose.
