SUPREMATouch
During normal operation, only one of the first three LEDs is on. If no LED is on, there is a problem
with the voltage supply to the module.
If the FAIL LED (LED No. 4) is on, contact an MSA service technician. If this cannot be done imme-
diately, the module can be replaced if a spare unit is available (
→
failure which occurred is stored in the SUPREMATouch logbook and can be found in the “Diag-
nosis/Logbook/System events” menu.
6.2
Replacing Modules
When a module is found to be defective, it must be replaced.
MSA recommends that an MSA service technician is called in to help with the diagnosis and to
help determine whether the module has to be replaced.
NOTICE
Only replace plug-in modules after the voltage to the SUPREMATouch system has been shut off.
Always disconnect the supply voltages before removing/inserting any plug-in modules.
In the following, the procedure for replacing individual modules is described.
Plug-In Modules
Replacing MCP and MDO Modules
The voltage to the system must be shut off before these modules can be replaced.
(1) Save the current system configuration [setup/measuring points, relay outputs, system] with
the SUPREMA Manager.
(2) Remove power from the system [e.g., by disconnecting the supply voltage connections at the
MIB module].
NOTICE
When rail-mounted relay modules are being used, the triggering of an alarm associated with the
shut-off of the voltage can be prevented by locking the relays on the MRC TS module, provided
that the MRC TS module is supplied with a voltage separate from that of the system [Chapter
12.10 "Connecting the Relay Outputs"]
(3) Replace the MCP20, or MDC20 and MDO20 modules [be careful with the ribbon cable
connection between the MDC20 and the MDO20 modules].
(4) Turn the voltage supply back on.
(5) Reconfigure the system.
(6) Unlock the relays again if necessary.
LED-No.
Colour Function
1
green
ON:
The external voltage supply is selected by the module.
2
green
ON:
The internal voltage supply is selected by the module.
3
green
ON:
The battery voltage supply is selected by the module.
4
red
ON:
A failure has occurred in the module.
5
green
ON:
The module’s CAN bus communications are proceeding
correctly.
6
yellow
ON:
System fail
7
yellow
ON:
Voltage fail
8
red
ON:
Module is in reset state
When replacing modules, ensure that the DIP switches are in the correct position
(see chapter 12.6 "Module Configuration").
