Installation and Startup of CI 3000 / SIOX

5.5.3 SIOX - Connecting to energy, gas and water meters
Only meters having a S0 interface are supported (reed contact or 24 V DC transistor output). Compared to reed
contact meters, polarity needs to be observed when connected transistor-output meters. The SIOX Extension
Module provides 24 V DC at terminals 93 (-) and 94 (+) for power supply to the S0 interface:
The digital inputs required for this purpose must be configured by jumpers as 24 V AC inputs (see
Section 4.3.1).
Warning - hazardous electrical voltage!
Danger external voltage!
Jumpers must always be configured while disconnected from power and
with connectors removed from inputs (terminals A1, A2 / to / L1, L2), because these terminals may
carry 230 V AC power!
Praxis TIP
What can be done in the event of chattering relay contacts: Relay contacts have the disadvantage that
they can chatter as a consequence of their mechanical construction. When activated a force is applied to the
contact which enables it to open and close, covering a distance in the micro-millimetre range.
Consequence: Repeated impulses at the S0 input, which generally results in excessive values at the electri­
city meter!
Diagnosis options: Reading off the impulses in menu 6-2 - the incoming impulses are displayed 3 times to
the right: If the impulses count e.g. 10, 12, 14, 15, 17.... then this is an indication of chattering contacts.
Remedy: With the parameter „Delay“ under menu 6-1-1 it is possible to increase the delay time for the con­
tact’s’ pulse edges.
Configuring meter and transformer constant (Menu 6-1-6-1):
1. Meter constant (pulses per kWh or m
3
)
2. Unit (kWh or m
3
)
2. Transformer constant (conversion ratio of current transformer)
Allowance must be made for the meter and transformer constant settings when using electronic me­
ters, as otherwise energy evaluation by the CI 3000 Store Computer will be inaccurate due to faulty
meter and transformer ratios!
