INSTALLATION INSTRUCTIONS
The Z112A module is designed for installation on a DIN 46277 guide, in
vertical position.
For efficient operation and long-life, the modules must be adequately
ventilated. Do not install any raceways or place other objects that could
obstruct the ventilation slits.
Do not install the modules above heat generating appliances – we
advise you to install the modules in the lower part of the panel.
SEVERE OPERATING CONDITIONS:
These are considered
severe operating conditions:
High supply voltage (> 30Vdc / > 26 Vac).
Sensor powered at input.
If the modules are installed side-by-side, it may be necessary to
separate them by at least 5 mm in the following cases:
If panel temperature exceeds 45°C and at least one of the severe
operating conditions occurs.
panel temperature exceeds 35°C and at least two of the severe
operating conditions occur.
ELECTRICAL CONNECTIONS
You are recommended to use shielded cables for connection of signals
– the shield must be connected to an earthing point giving priority to the
instrumentation. Moreover, we advise you not to route the conductors
near to power cables serving inverters, motors, induction ovens, etc.
PRE-SETTING THE DIVIDER
By means of the dip switches at the side, the instrument can be pre-set to repeat at
output all the pulses received at input or to divide the pulses received at input by a
whole number between 2 and 256.
If the divider is used, the dip switches from D1 to D8 must be set as shown in the
following table to obtain the required division factor.
