G e n e r a l i nf o r ma t i o n :
For application in refrigeration systems and heat
pumps.
S a f e ty i n s tr u c t i o n s :
•
Read operating instructions thoroughly. Failure
to comply can result in device failure, system
damage or personal injury.
•
According to EN 13313 it is intended for use by
persons having the appropriate knowledge and
skill.
•
Before opening any system make sure pressure in
system is brought to and remains at atmospheric
pressure.
•
Do not exceed the specified maximum ratings for
pressure, temperature, voltage and current.
•
Do not exceed max. bulb temperature.
•
Before installation or service disconnect all
voltages from system and device.
•
Ensure that design, installation and operation are
according to European and national
standards/regulations.

•
TS1 temperature switches are equipped with a SPDT
snap action contact switching from 1-2 to 1-4 on
rising and from 1-4 to 1-2 on falling temperature.
Reaching the preset switch point on rising
temperature, contact 1-2 breaks while contact 1-4
makes and vice versa on falling temperature.
TS1 with manual reset:
•
Reaching the preset switching point contact 1-4
breaks (low temp. switch) or contact 1-2 makes
(high temp. switch) and locks in this position. After
the temperature has risen or dropped by a fixed
differential,
the switch can be reset by pushing the
reset button.
•
TS1 with manual reset are “trip-free”.
M o u n t i n g l o c a t i o n / di r e c t i o n :
Any direction except upside down.
I n s t a l l a t i o n a l l mo d e l s , e xc e p t T S1 -
G / H ( F i g . 2 a ) :
•
TS1 controls may be installed by using a mounting
plate or as a wall-mounted device against a flat
surface.
•
For wall-mounted devices, the insulating console
supplied with controls with sensor type “E” must
be installed between wall and control to ensure
proper operation.
•
For devices with vapor charges “A” and “P” an
insulating console or other insulating material
must be used if the wall temperature is close to
the application temperature to be sensed.
•
Use universal thread M4 or UNC8-32 mounting
holes for installation via mounting plate.
•
Use the standard mounting holes at the backside for
wall mounting.
•
Use mounting screws supplied with control.
•
Mounting screws must not penetrate control
backside by more than 8 mm to ensure proper
operation.
•
In order to achieve protection class IP44, the
following instructions must be observed:
-
Cover must be closed, and cover screw fastened.
-
Control must be mounted against a flat surface so
that all openings on the housing backside are
fully covered.
I n s t a l l a t i o n mo d e l s T S1 - G/ H ( F i g . 2 b ) :
•
Prepare cut out section for 85 x 39 mm
•
Prepare holes for M4 screws
•
Insert control into slot and tighten screws
I n s t a l l a t i o n T e mp e r a t u r e s e n s o r
( F i g . 3 ) :
•
Avoid sharp bends or kinks in capillaries.
•
Do not allow capillary to rub and abrade against any
moving surface. Avoid work hardening effects.
•
A capillary loop of ca. 8 cm diameter should be
provided in capillary type sensors (A, C, P) below
the control.
•
Vapor charges (Sensor types A, E, P):
•
These sensing elements always sense from the
coldest point on the capillary, coil, bulb or power
element head.
•
Ensure that the control body and the portion of the
capillary which is not at the sensing location is
warmer than the sensing location by at least 2 K.
•
Surfaces mounted controls should use an insulating
console in order to ensure that control is not affected
by the temperature of the mounting surface.
•
At least 30 cm of sensor type “P” should be located
at the sensing point for proper control.
Adsorption charge (Sensor type “F”):
•
This sensing element always responds to the bulb
temp.
•
The entire bulb must be in contact with the sensed
temp.
•
This charge is slower in response than a vapor
charge.
E l e c t r i c a l c o n ne c t i o n ( F i g . 4 ) :
•
Note: Comply with local electrical regulations
when conducting electrical wiring. Wire size
must match the electrical load connected to the
switch contacts.
•
Feed cables through rubber grommet at switch
bottom.
•
Optionally, replace rubber grommet by a standard
PG 13.5 cable gland.
•
Connect wires to terminals 1, 2 and 4 by taking into
account switch functions as shown in Fig. 1a to 1e.
•
Fasten terminal screws with torque 1.2 Nm.
•
For electronic applications with low electrical loads
(voltage <24 V and current <50 mA) gold plated
contacts are recommended.
S e t p o i n t a d j u s t me n t ( F i g . 4 , F i g . 5 ) :
•
TS1 pressure switches come with individually
adjustable range and differential depending on the
exact model.
•
Manual reset switches always has a fixed
differential.
•
Use the adjustment knob, a flat screw driver or a ¼”
refrigeration (square) wrench to adjust setpoints as
described below.
•
Adjust upper setpoint using the range spindle.
•
Adjust lower setpoint by turning the differential
spindle:
•
Upper setpoint – Differential = Lower setpoint
•
A separate thermometer must be used for exact
adjustment of the setpoints. The integrated display
scale can only be used for obtaining approximate
settings.
•
Refer to the General Product Guide for standard
factory settings.
•
Minimum differential setting at the end of range do
differ slightly from the nominal differentials.
M a n u a l r e s e t (F i g . 6 )
•
Manual reset: press the reset button.
Note that the reset is ‘trip-free’, i.e. reset is only
possible if the temperature has reached its reset
treshold.
Off-switch (Fig.1e)
•
TS1-B/F/H have an off-switch which cuts off the
line to terminal 1 when in Position “STOP”.
C h e c k- o u t l e v e r ( F i g . 4 )
•
Use the check-out lever to manually override the
electrical contact position for testing out the system.
