3 - INSTALLATION
MECHANICAL MOUNTING
:
The instrument, in DIN case 96 x 96 mm,
is designed for panel mounting. Make an hole 90 x 90 mm and insert the
instrument, fixing it with the provided special brackets . We recommend to
mount the gasket to obtain an IP 54 front protection. Avoid to place the
instrument in areas with humidity or dirt. Connect the instrument as far as
possible from source of electromagnetic disturbances so as motors, power
relays, relays, electrovalves,etc.
ELECTRICAL CONNECTIONS
: Carry out the electrical wiring
connecting only one wire for each terminal , according to the following
diagram, check that the power supply is the same as indicated on the
instrument and the loads current is not upper than the maximum current
admitted. The instrument, being a built in equipment with permanent
connection into a cabinet, is not furnished with internal device protecting
from overcurrent : it's recommended , therefore, to properly protect all the
electric circuits connected to the instrument, with devices (ex. fuses)
proportionate to the circulating currents. It's strongly recommended to use
cables with proper insulation, according to the working voltages and
temperatures. Furthermore, the input cable of the probe has to be kept
separate from line voltage wiring. If the input cable of the probe is
screened, it has to be connected on the ground with only one side. It is
advisable to check that the parameters are those desired before connecting
the outputs to the actuators so as to avoid malfunctioning . Whenever a
failure of the instrument could cause dangerous or damaging situations, it
should be kept in mind that the plant has to be provided with additional
devices to ensure the safety.
4 - OPERATING MODE
4.1 - ON/OFF CONTROL
The control mode of the instrument by ON/OFF mode occours on the
outputs according to the Sets point fixed, to the differential switching
points (par. "d1", "d2") and to operating modes (par. "HC1", "HC2")
programmed. For a correct functioning it is necessary to set a negative
differential switching point for reverse controls (ex.Heating processes) and
