MEDICS
includes:
AC and 3(N)AC changeover and monitoring modules. Examples of modules in the MEDICS
tem include UMC..., USC..., UFC... and EDS.... insulation fault location systems.
Display and operating units such as alarm indicator and operator panels or alarm indicator and
test combinations.
Communication between these components takes place via the BMS bus (two-wire connec-
tion).
The connection of third-party technical equipment by means of protocol converters (gate-
ways), via digital inputs and relay outputs.
The real strength of MEDICS
ponents and the resulting information provided to the user. Readiness for operation is mon-
itored continuously. Operating states, irregularities, faults and equipment failures are
displayed. From the user's point of view, this means high operational reliability.
3.2 UMC107E.. features
The UMC107E-.. changeover and monitoring module has the following features:
Two-pole changeover with contactors. Both contactors have a mechanical latching.
Voltage monitoring on the preferred supply (line 1)
Voltage monitoring on the second supply (line 2)
Voltage monitoring at the output of the changeover and monitoring module (line 3)
Monitoring of the switching elements to ensure that they are in the correct switching state and
for wire breaks (connecting wires, contactor coil, coil for latching module)
Internal functional testing including checking of the changeover times
Monitoring of the insulation resistance in the IT system
Monitoring of the IT system transformer load current
Monitoring of the IT system transformer load temperature
Monitoring of the A-ISOMETER® 107TD47 connecting wires
Communication of components with one another via BMS bus
Communication with remote alarm indicator and test combinations and TM alarm indicator
and operator panels via BMS bus
Possibility to set the time delay for the changeover in 50 ms increments for adaptation to the
total off-time acc. to DIN VDE 0100-710 (VDE 0100 Part 710):2002-11, section 710.537.6.2k
Can be used in systems in accordance with IEC 60364-7-710:2002-11, sections 556.5.2.2, 556.7
and 556.8 and DIN VDE 0100-710 (VDE 0100 Part 710):2002-11, section 710.564.6 with a change-
over period = 15 s or = 0.5 s
The MEDICS
assembly. Do not make any changes to the components, their password-pro-
tected settings or the wiring without consulting Bender first.
In each case you should make the settings that are required for adaptation to the
