8.4 Commissioning
The synchronization signal must be connected to the synchronization input of the SIMEAS R-
PMU (terminals 7B1 and 7B2, see chapter 14.3.4.1) observing the correct polarity. The signal
must have a level of DC 24 V.
Note
Observe that due to your order of the SIMEAS R-PMU the synchronization input is always
designed for the level of the synchronization signal even if the nominal level of the remaining
binary inputs of the CPU is different! The polarity of the synchronization signal must be observed
even if the other binary inputs are bipolar!
Select GPS/DCF77, Sync-Box or Minute pulse in the OSCOP parameterization mask
"SIMEAS R-PMU"
must be entered under "External delay time, synchronization pulse". 0 µs can be entered for
the test mode.
After the initial start of the device, watch LED 5 "Synchronization error" and LED 13 "Device
synchronized" at the front panel. As soon as LED 13 starts flashing, a valid synchronization
signal has been detected. If LED 13 is permanently lits, the measuring system has been adapted
to the synchronization signal and the device is synchronized.
Note
The functions "Synchronization error" (LED 5) and "Device synchronized" (LED 13) have been
set on delivery, but another parameterization may be used.
Note
Synchronization adjustment of the measuring system can take up to 45 minutes!
In the event of a permanent synchronization signal fault, LED 5 "Synchronization error" lights up.
An analysis of the log recorder data and evaluation of the SIMEAS R-PMU status messages may
be helpful during the fault location. See also chapter 8.5, "Fault Handling".
