When using the DIN rail connector, first place it into the DIN rail (see A – C). It is used to bridge the power supply. It is also absolutely vital that you snap the module and the DIN rail connector into position in the correct direction: the snap-on foot should be at the bottom and the connector on the left.

PHOENIX CONTACT 7 MINI MCR-SL-FM-RC-NC 7 Fault monitoring FM Fault monitoring simplifies error evaluation in multi-channel isolation amplifier applications using a group error message. 7.1 • • Fault monitoring for group error detection Use MINI Analog signal conditioners that support fault monitoring. Connect these signal conditioners to the MINI MCR-SLFM-RC(-SP)-NC fault monitoring module via the DIN rail connector . Detected errors on the signal input of a MINI Analog isolation amplifier or in the isolation amplifier are reported to the fault monitoring module via the DIN rail connector. The module reports the error centrally via an N/C contact. 7.2 Fault monitoring for redundancy monitoring With "supply via power terminal", the fault monitoring module can be used to monitor the supply voltage in the group. Failure of the supply voltage generates a central message via an N/C contact. • Install a power terminal and a fault monitoring module of the same shape side-by-side without spacing. • Bridge terminals 1 to 4 of the power terminal with terminals 1 to 4 of the fault monitoring module. Use the provided plug-in bridges FB S2-6 (Order No. 3030336) or normal cables. For additional mechanical redundancy, two power terminals and two fault monitoring modules can be used. Only one supply may be connected to each power terminal. In the second fault monitoring module, fault monitoring of external measuring transducers must be deactivated because evaluation can only take place via a module in a group. 7.3 – – – Application options When using a power terminal in combination with a fault monitoring module on the DIN rail connector: Redundant voltage supply on the DIN rail connector is possible, redundancy can be monitored, the group error can be evaluated. When using a fault monitoring module without power terminal in the DIN rail connector: Group errors can be monitored only. When using a power terminal in combination with a fault monitoring module without DIN rail connector: Redundancy of two supply voltages can be monitored. 105448_en_00 PHOENIX CONTACT 8 MINI MCR-SL-FM-RC-NC 8 Configuration At delivery, all DIP switches are in the "OFF" position. This corresponds to the following standard configuration: – Group error detection “on” – Redundancy monitoring “on” – Relay “active” DIP switch S1 is used to activate and deactivate group error detection, redundancy monitoring of the supply voltages, and the relay. Configure the DIP switches according to the planned application using the configuration tables. The module can also be configured with the supply voltage not connected.
