Type 402-
402 has 2 extra pulse inputs, VA and VB, which are placed on the modules (see paragraph 11.3 for
further details).

Reconfiguration between pulse inputs and pulse outputs is not necessary with MULTICAL
®
402. When a module
with pulse inputs is mounted in MULTICAL
®
402, the meter is automatically configured for pulse inputs.
The inputs are configured via the FF and GG codes as shown in the table below. In the absence of other
information from the customer the inputs will be configured as FF=24 and GG=24. After delivery the FF and GG
codes can be changed by means of the PC program METERTOOL (see paragraph 14).

3.6.1 Pulse inputs VA and VB
MULTICAL

Pulse inputs VA and VB function independently of the meter itself. Therefore their values are not included in any
kind of energy calculation.
402 has two extra pulse inputs, VA and VB, for collection and remote totalization of pulses from e.g.
mechanical water meters. The pulse inputs are physically placed on the modules, e.g. the ”data/pulse input
module”, which can be mounted in the module base, but accumulation and data logging of values is carried out
by the calculator.
