5. Commissioning, settings and testing

5.1 Setting and testing according to the checklist

A total changeover time of t ≤ 0.5 s and switching back within five seconds to the preferred
supply on voltage recovery is factory set.
The response time t(off), the idle time t(K1-2) and the return transfer time t(on) of the
UMC107E-.. can be set and must be adjusted in line with the requirements of the specific
application, the short-circuit calculation and the requirements of 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, sec-
tion 710.537.6 (automatic changeover modules).
The total off time permitted to occur (from the point at which the fault occurs until the arc in
the overcurrent protective device is cleared) must be less than the minimum time delay for the
changeover process of the automatic changeover module. Setting: Response time t(off)
If several changeover modules are connected in series in a power supply system, it is recom-
mended that they be time-graded. Setting: Response time t(off), idle time t(K1-2) and return
transfer time t(on).
As part of the response delay (to be custom-set), you must, at the very least, take into account
the periods of time when the circuit experiences short interruptions, and the response times of
the short-circuit protective device connected upstream or downstream. Regardless of this, the
idle time for the changeover process corresponding to the place of installation must be consid-
ered to prevent switching overvoltages.
Setting: Response time t(off) and idle time t(K1-2).
For this purpose, please consult the changeover time lapse diagram in the instruction leaflet
for the PRC487 control device and make the settings required according to the description.
You will find a checklist in chapter "9. Manufacturer's certificate, checklist, circuit documen-
tation". This list details the factory settings and the system-specific settings for the MEDICS
module. Please carry out all the work outlined in the list and log each test step.
The checklist contains:
Visual inspection
Commissioning, settings, factory settings
Functional test
Keep this checklist with this manual in a location that is close to the MEDICS

Avoiding errors

Communication via the BMS bus can only be guaranteed when there is only one
terminating resistor at the beginning and the end of the BMS bus. Additional ter-
minating resistors can lead to malfunctions and therefore must not be used.
Please also note the information in the "BMS bus" instruction leaflet.
