This display is used for general indication of the start up states in the MC100 and for various other
purposes.
5.3.1 Start up states:
P4/P5 Description Note
S U Initial start up state
S.U. Internal communications started
S.0. Start initialisation of the fieldbus module Short state if no errors
S.1. Cyclic data now exchangeable with the network Short state if no errors
S.2. MC100 ready and waiting for connection
S.3. Intermediate state / special network state Short state
S.4. Connection to network established and working Short state
S.5. Internal error during initialization Steady state (see trouble shooting)
S.7. Internal error during initialization Steady state (see trouble shooting)
S 8 Factory Reset to default – initiating from Dipswitch
S 9 Factory Reset to default
5.3.2 Network address
After initialization, the display is showing the network node address.
5.3.3 Alarm- and warning display
The node address is replaced by a flashing:
AL and the alarm number XX, when and alarm is present (see 8.1.1 Alarms).
Er and the warning number XX, when a warning (recoverable alarm) is present (see 8.1.2 warnings).
5.3.4 Dipswitch
The dipswitch on the right side of the MC100 module can used to do a factory-reset function.
Reset state Dipswitch Action Description
0 All OFF None Normal runtime state
1 All OFF Remove power to MC100
2 SW 8 ON Apply power to MC100
MC100 starts up and reaches init state 2
And the restart again initializing to factory
defaults and starts up.
3 SW 8 ON Remove power to MC100
4 SW 8 OFF Apply power to MC100 MC100 starts up normally
The factory reset can be necessary to do before trying to connect to fieldbus network.
During the factory reset initialization, the MC100 determines how many and what pump types are
connected on the Flexnet. Based on this, the MC100 determines the number of cyclic data bytes to be
exchanged on the fieldbus, which MUST be set to same number in the fieldbus network configuration
(see 6.x.x).
