The controller has 5 temperature sensor inputs (which can also be used as digital inputs) and 5
relays. If more inputs or relays are necessary, the controller can be expanded with an optional
907.100054 MC3-EM [1Do12,1Rth16] extension module. That adds 11 temperature sensor inputs
and 12 relays to the controller.
1.2 Commissioning
The following must be taken into account before the controller is commissioned:
·
When the Ethernet connection is used, the IP address must be checked/defined (see section
5.1).
·
The correct mode (FC or MC) must be selected (see section 5.2)
·
The desired controller name must be defined (see section 5.3).
·
The desired input and output functions must be defined with parameters (see section 3, with
name parameters P101
1 ..P116 and P951..P964).
·
If the controller must work together with other controllers, the controllers must be linked to
each other through the RS485 network. Then a network number (P801) must be defined on
every controller.
·
The other parameters must be checked/defined.
The software version number of the controller can be retrieved using parameter P991. To
ensure that multiple controllers can work together in a single network, it is recommended that
controllers with similar software versions are used. Controllers with different software versions
do not always work well together.
In addition, we strongly recommend that after a controller has been commissioned you
carefully note down the defined parameters and store them in a safe place. Then, if a controller
needs to be exchanged, that can be done much faster and more easily.
The functional operation of the controller is described in the following sections.
1 In this user guide, parameters are indicated with P<x>, where x = the parameter number.
