MOUNTING REQUIREMENTS
Select a mounting location where there is
minimum vibration and the ambient temperature
range between 0 and 50 °C (32 and 122 °F).
The instrument can be mounted on a panel up to
15 mm thick with a square cutout of 45 x 45 mm.
For outline and cutout dimensions refer to page IV.
The surface texture of the panel must be better
than 6.3 mm.
The instrument is shipped with rubber panel
gasket.
To assure the IP65 and NEMA 4 protection, insert
the panel gasket between the instrument and the
panel as show in fig. 1.
While holding the instrument against the panel
proceed as follows:
1) insert the gasket in the instrument case;
2) insert the instrument in the panel cutout;
3) pushing the instrument against the panel, insert
the mounting bracket;
4) with a screwdriver, turn the screws with a
torque between 2.7 to 3.5 in-lb (0.3 and 0.4
Nm).

A) MEASURING INPUTS
NOTE: Any external components (like zener
barriers etc.) connected between sensor and input
terminals may cause errors in measurement due
to excessive and/or not balanced line resistance or
possible leakage currents.
TC INPUT
Fig. 4 THERMOCOUPLE INPUT WIRING
NOTE:
1) Don’t run input wires together with power
cables.
2) For TC wiring use proper compensating cable
(for example, J TC extension wire for J TC)
preferable shielded.
3) when a shielded cable is used, it should be
connected at one point only.

CONNECTION DIAGRAMS
Connections are to be made with the instrument
housing installed in its proper location.

RTD INPUT
Fig. 5 RTD INPUT WIRING
NOTE:
1) Don’t run input wires together with power
cables.
2) Pay attention to the line resistance; a high line
resistance may cause measurement errors.
3) When shielded cable is used, it should be
grounded at one side only to avoid ground loop
currents.
4) The resistance of the 3 wires must be the
same. Use the same gauge wire for all three
conductors.

B) RELAY OUTPUTS
Fig. 6 RELAY OUTPUT WIRING
The OUT 1 NO contact and the OUT 2 contact are
protected by varistor against inductive load with
inductive component up to 0.5 A.
The contact rating of the OUT 1 is 3A/250V AC on
resistive load.
The contact rating of the OUT 2 is 1A/250V AC on
resistive load.
The number of operations is 1 x 105 at specified
rating.
NOTES 1) To avoid electric shock, connect power
line at the end of the wiring procedure.
2) For power connections use No 16 AWG
or larger wires rated for at last 75 °C
(167°F).
3) Use copper conductors only.
4) Don’t run input wires together with power
cables.
The following recommendations avoid serious
problems which may occur, when using relay
output for driving inductive loads.

VOLTAGE OUTPUTS FOR SSR DRIVE
Fig. 8 SSR DRIVE OUTPUT WIRING
It is a time proportioning output.
Logic level 0: Vout < 0.5 V DC.
Logic level 1:
- 14 V
+ 20 % @ 20 mA
- 24 V
+ 20 % @ 1 mA.
Maximum current = 20 mA.
NOTE: This output is not isolated.
A double or reinforced Isolation between instrument
output and power supply must be provided by the
external solid state relay.
SOLID STATE
RELAY
INDUCTIVE LOADS
High voltage transients may occur when switching
inductive loads.
Through the internal contacts these transients may
introduce disturbances which can affect the
performance of the instrument.
The internal protection (varistor) assures a correct
protection up to 0.5 A of inductive component but
the OUT 1 NC contact is not protected.
The same problem may occur when a switch is
used in series with the internal contacts as shown
in Fig. 7.
Fig. 7 EXTERNAL SWITCH IN SERIES WITH
THE INTERNAL CONTACT
In this cases it is recommended to install an
additional RC network across the external contact
as show in Fig. 7 (Chromalox snubber PN 014901305 is recommended).
The value of capacitor (C) and resistor (R) are
shown in the following table.
Anyway the cable involved in relay output wiring
must be as far away as possible from input or
communication cables.

GENERAL OPERATION
Theree are two setup modes for the 1601
- Configuration mode
- Operator mode
In general the configuration mode is the initial
setup of the controller when first installed. Input
type and alarm setup are examples of Configuration mode setting. The operator mode includes
settings that might be adjusted frequently with
daily control operations such as set points and PID
parameters.
CONFIGURATION MODE
PRELIMINARY HARDWARE
SETTINGS FOR CONFIGURATION
1) Remove the instrument from its case.
2) Set the internal switch V2 in open condition

A) POWER LINE WIRING
Fig. 3 POWER LINE WIRING
NOTE:
1) Before connecting the instrument to the power
line, make sure that line voltage corresponds to
the description on the identification label.
2) To avoid electric shock, connect power line at the
end of the wiring procedure.
3) For supply connections use No 16 AWG or larger
wires rated for at last 75 °C (167°F).
4) Use copper conductors only.
5) Don’t run input wires together with power cables.
6) For 24 V AC/DC the polarity is not important.
7) The power supply input has NO fuse protection.
Please, provide externally a T type 1A, 250 V fuse.
8) The safety requirements for Permanently Connected Equipment are:
- a switch or circuit-breaker shall be included in the
building installation;
- It shall be in close proximity to the equipment and
within easy reach of the operator;
- it shall be marked as the disconnecting device for
the equipment.
NOTE: a single switch or circuit-breaker can drive
more than one instrument.
