1200/1300
CONTROLLER
cod. 80309 - 01/2014 - ENG
1 • DIMENSIONS AND CUT-OUT; PANEL MOUNTING
This section contains the instructions necessary for
correct installation of the 1200/1300 controllers into the
machine control panel or the host system and for correct
connection of the controller power supply, inputs, outputs
and interfaces.
Before proceeding with installation read the
following warnings carefully!
Remember that lack of observation of these warnings
could lead to problems of electrical safety and
electromagnetic compatibility, as well as invalidating
the warranty.
Electrical power supply
• the controller is NOT equipped with an On/Off switch: the user
must provide a two-phase disconnecting switch that conforms
to the required safety standard (CE marking), to cut off the
power supply upstream of the controller.
The switch must be located in the immediate vicinity of the
controller and must be within easy reach of the operator. One
switch may control more than one controller.
• if the controller is connected to NOT isolated electrical
equipment (e.g. thermocouples), the earth connection must be
made with a specific conductor to prevent the connection itself
from coming directly through the machine structure.
• if the controller is used in applications with risk of damage to
persons, machinery or materials, it is essential to connect it up
to auxiliary alarm equipment. It is advisable to make sure that
alarm signals are also triggered during normal operation.
The controller must NOT be installed in flammable or explosive
environments; it may be connected to equipment operating
in such atmospheres only by means of appropriate and
adequate types of interface, conforming to the applicable safety
standards.
Notes Concerning Electrical Safety and
Electromagnetic Compatibility:
CE MARKING:
The instrument conforms to the European Directives 2004/108/
CE and 2006/95/CE with reference to the generic standards:
EN 61000-6-2 (immunity in industrial environment) EN 61000-6-3
(emission in residential environment) EN 61010-1 (safety).
Series 1200/1300 temperature controllers are mainly designed to
operate in industrial environments, installed on the switchboards
or control panels of productive process machines or plants.
Advice for Correct Installation for EMC
Instrument power supply
• The power supply to the electronic equipment on the
switchboards must always come directly from an isolation
device with a fuse for the instrument part.
• The electronic instruments and electromechanical power
devices such as relays, contactors, solenoid valves, etc., must
always be powered by separate lines.
• When the electronic instrument power supply is strongly
disturbed by the commutation of transistor or power units
or motors, an isolation transformer should be used for the
controllers only, earthing the screen.
• It is essential that the plant has a good earth connection:
- the voltage between neutral and earth must not be >1V
- the Ohmic resistance must be <6W;
• If the mains voltage fluctuates strongly, use a voltage stabilizer.
• In the proximity of high frequency generators or arc welders,
use adequate mains filters.
• The power supply lines must be separate from the instrument
input and output ones.
Inputs and outputs connection
• The externally connected circuits must be doubly isolated.
• To connect the analogue inputs (TC, RTD) the following is
necessary:
- physically separate the input cables from those of the power
supply, the outputs and the power connections.
- use woven and screened cables, with the screen earthed in
one point only
• To connect the regulating and alarm outputs (contactors,
solenoid valves, motors, fans, etc.), fit RC groups (resistance
and condensers in series) in parallel to the inductive loads that
operate in Alternating Current.
(Note: all the condensers must conform to VDE (class X2)
standards and withstand a voltage of at least 220V AC. The
resistances must be at least 2W).
• Fit a 1N4007 diode in parallel with the coil of this can be
removed inductive loads that operate in Direct Current.
GEFRAN S.p.A. declines all responsibility for any
damage to persons or property caused by tampering,
neglect, improper use or any use which does not
conform to the characteristics of the controller and to
the indica tions given in these Instructions for Use.
Warnings and instructions for mounting to the panel
Instructions for installation category II, pollution
level 2, double isolation.
• only for low power supply: supply from Class 2 or low voltage
limited energy source.
• the power supply lines must be separate from the controller
input and output ones
• group the instruments together keeping them separate from the
powered part of the relay
• do not install high-power remote switches, contactors, relays,
thyristor power units (especially the “phase angle” type),
motors, etc. in the same switchboard
• avoid dust, humidity, corrosive gasses and heat sources
• do not block the ventilation holes: the working temperature
must be between 0...50°C
• surrounding air: 50°C
• use 60/75°C copper (Cu) conductor only, wire size range 2x No
22 - 14AWG, Solid/Stranded
• use terminal tightening torque 0.5N m
Nominal ambient conditions
Before supplying the Controller with power, make
sure that the mains voltage is the same as that
shown in the last number of the order code.

Always make the connections using cable types suitable for
the voltage and current limits given in Section 5 - Technical

If the Controller has faston terminals these must be protected and
isolated.
If it has screw terminals, the wires must be attached, at least in pairs
