The tariff changeover is carried
out by the internal time program
"z".
For devices with the auxiliary voltage of "85 .. 265VAC,
120 .. 370VDC" the auxiliary input is activated with an
alternating voltage of 85 .. 265VAC .
CONF
For devices with an auxiliary voltage of "15 .. 55VAC, 20
.. 80VDC" the auxiliary input is activated with an alter-
nating voltage of 15 .. 55VAC or a direct current
voltage of 20 .. 80VDC.
For devices with an auxiliary voltage of "40.. 115VAC,
55.. 165VDC" the auxiliary input is activated with an
alternating voltage of 40.. 115VAC or a direct current
voltage of 55.. 165VDC.

Programming
The external digital inputs can only be indicated and
programmed, if the protocol "06" (Modbus RTU Master)
is set at the UMG503.
The functions
- Reset real power EMAX,
- Tariff changeover and
- Synchronization of internal clock
can be programmed according to the table "assignment
of auxiliary inputs" on page 50.
Attention!
The wiring for the auxiliary input must be suitable for
voltages up to 300VAC against ground.
On the internal auxiliary input,
only the tariff changeover is ac-
tive.
