11 Startup
NOTE: High voltages can be present in the MSP module and at the relay terminals of the relay
modules. Suitable safety measures must be taken when starting up the system.
Startup procedures may be performed only by authorized and qualified personnel.
Before startup, it must be ensured that all installation steps have been executed properly and that
the cable connections and configurations of the individual modules as well as of the entire system
are correct.
Startup is to be performed by executing the following steps:
- Make sure that the voltage supply is turned off.
- Check to make sure that the sensor, relay, switching output, and analog output connections of
the system are disconnected.
- Ensure that all the required modules have been properly mounted in the system and are con-
nected to each other.
- In systems with several racks, make sure the CAN bus connection is correct (cabling,
baudrate, CAN node no., terminating resistor).
- Turn on the supply voltage.
- System Configuration (SUPREMA Manager)
- Connect and configure the sensors.
- Connect and configure the relay or switching outputs.
- Give the sensors a first calibration.
- Subject the overall system to a function test with gas.
11.1 Turn On the Supply Voltage
Turn on the supply voltage to the system under consideration of all relevant safety measures. Af-
ter the power is turned on, the message “SUPREMA - MDO-20” appears on the display of the front
panel (MDO module) along with the current software and hardware revision. During the start-up,
a self-test is performed. The progress of this self-test is indicated by a successive activation of all
LEDs as an binary counter. When a communication between the MDO and the MCP(s) is estab-
lished, all alarm LEDs will be switched off. After the module has run through a self-test, it starts
the system with the message “system start in progress”. After the system starts successfully, the
number of inputs corresponding to the plugged-in MAI modules is displayed in the “Measure/List”
menu.
NOTE: If this process is not completed in 5 minutes, the installation should be checked again. If
necessary, an MSA service technician should be called in to correct the problem.
