2.3 General hazard warnings
STOP
With assembly, operation and maintenance of the industrial contoller it has to be made sure
that the entire drive train is secured against accidental switch-on and the plant is
unpressurized. You may be seriously hurt by hot or pressurized hydraulic oil or water. Make
absolutely sure to read through and observe the following safety indications.
• All operations on and with the industrial controller have to be performed taking into account "safety first".
• Make sure to switch off the power pack before you perform your work on the industrial controller.
• Secure the power pack against accidental switch-on, e. g. by providing warning signs at the place of switch-on
or removing the fuse for current supply.
• Do not reach into the operating area of the machine as long as it is in operation.
• Remove the fuse for power supply before you perform your work on the industrial controller.

Advice
2.4 Intended use
You may only assemble, operate and maintain the industrial controller if you
• have carefully read through the operating/assembly instructions and understood them
• are technically qualified and specifically trained (e. g. safety, environment, logistics)
• are authorized by your company
The industrial controller may only be used in accordance with the technical data (see chapter 1). Unauthorized
modifications on the industrial controller are not admissible. We will not assume liability for any damage that may
arise. In the interest of further development we reserve the right for technical modifications.
The industrial controller IR described in here corresponds to the state-of-the-art at the time of printing of these
operating/assembly instructions.
3
Storage, transport and packaging
3.1 Storage
The industrial controllers are supplied in preserved condition and can be stored in a dry and roofed place for
6 - 9 months.
The features of the industrial controller remain unchanged for up to 5 years with favourable storage conditions.
!
The storage rooms must not include any ozone-generating devices like e. g. fluorescent
light sources, mercury-vapour lamps or electrical high-voltage appliances.
Humid storage rooms are not suitable.
Make sure that condensation is not generated. The best relative air humidity is less than
65 %.
3.2 Transport and packaging
!
In order to avoid any injuries and any kind of damage always make use of proper transport
and lifting equipment.
The industrial controllers are packed differently each depending on size, number and kind of transport. Unless
otherwise contractually agreed, packaging will follow the in-house packaging specifications of KTR.

Assembly
4.1 Mode of operation
The KTR industrial controllers allow to measure the temperature of the hydraulic liquid precisely and control it
according to the specification.
Industrial controllers operate according to the principle of liquid expansion. The temperature probe is connected
with a membrane in the switching controller via a capillary tube. The expansion liquid in the probe unit changes its
volume immediatedly dependent on the temperature acting. The change of volume moves the membranes. The
motion of the membrane is transmitted to a snap-action switch (microswitch) via a lever mechanism. The
controller reacts accurately even with slow temperature changes. Vibrations do not affect the accuracy. The probe
and contact systems of the individual controllers are separated. The thermometers operate with a spring system
and a separate probe system. All probe systems are housed together in one immersion sleeve.

4.6 Installation
The place of installation should be readily accessible and low-vibration. The permissible
ambient temperature must be observed (consider potential thermal radiation). The
installation position of the thermostat is optional.
• Remove the immersion sleeve supplied from the device by turning the union screw connection.
!
Never turn the immersion sleeve only, since the capillary tube may be damaged.
• Screw in the immersion sleeve in the respective position (tank or pipe) and seal with a suitable sealing agent.
• Insert the probe in the immersion pipe and fix with the union nut.
The temperature probe must be inserted in the direction of flow and over its entire active
length. The probe end should have a clearance of approx. 10 mm in axial direction.
• Take off the housing cover by unscrewing the housing screws.
• Unscrew the fastening screws of the board and lift the board carefully.
!
The capillary tube may be damaged in this way.
