5.18 Dosage
The SU/SI output of the device can be used for performing time or energy dosage in combination with
a power source, as used during so-
called ‘dial-tests’ or ‘register tests’ of electricity meters.
SU and SI are passive relay contacts, which can be used to control the switch-on and switch-off of
voltages and currents of the power source in a meter test bench. They can be steered directly by
commands or by the reference meter during dosage functions. The contacts are normally closed in all
functions except during dosage function, where they are opened at start and closed at the end,
depending on the defined initial and end status of the contacts.
5.18.1 Dosage contacts SU/SI
SU and SI are potential free contacts located on device in Control connector. During energy and time
dosage operations are these contacts used to control a power source or to control the switching of
current and voltage.
Loading capacity of the contacts: max. 125V, 1A
