2 Safety

2.1 Intended Use

The GTH 2448 / …is a digital thermometer. The device must be used only according to its intended purpose and

under suitable conditions.

2.2 Safety signs and symbols

Warnings are labeled in this document with the followings signs:

DANGER

Caution! This symbol warns of imminent danger, death, serious

injuriesand significant damage to property at non-observance.



Attention! This symbol warns of possible dangers or dangerous

situations which can provoke damage to the device or environment at

non-observance.

Note! This symbol point out processes which can indirectly influence

operation or provoke unforeseen reactions at non-observance.

2.3 Safety guidelines

Make it a rule to always observe the following points to exclude any risk whatsoever for the operator.

1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to

any other climatic conditions than those stated under "Specification".

If the device is transported from a cold to a warm environment condensation may cause in a failure of the

function. In such a case make sure the device temperature has adjusted to the ambient temperature

before trying a new start-up.

2. If there is a risk whatsoever involved in running it, the device has to be switched off

immediately and to be marked accordingly to avoid re-starting.

Operator safety may be a risk if:

- there is visible damage to the device

- the device is not working as specified

- the device has been stored under unsuitable conditions for a longer time.

In case of doubt, please return device to manufacturer for repair or maintenance.

_____________________________________________________ _____________________________________________________________________________

3. When connecting the device to other devices the connection has to be designed most

thoroughly as internal connections in third-party devices (e.g. connection GND with

protective earth) may lead to undesired voltage potentials that can lead to malfunctions or

destroying of the device and the connected devices.

4. Do not use these products as safety or emergency stop devices or in any other application

where failure of the product could result in personal injury or material damage.

Failure to comply with these instructions could result in death or serious injury and material

damage.

5. When operating electric devices parts of these devices will, as a matter of course, be live.

Unless the warnings are observed severe damage to life and limb or to property may be

the result. Make sure that only skilled personnel are working with this device.

Trouble-free operation of this device can only be guaranteed if it is property transported

and stored. Careful installation, mounting, operation and maintenance are vital factors for

the safe operation of this device.

Skilled personnel:

These are persons who are familiar with the installation, mounting, commissioning and the operation of the

product and have acquired a qualification for their job:

- Training or instructions or qualification to switch on/off, isolate, ground and apply markings to circuits and

devices/systems in accordance with the latest state of the art standards of safety technology.

- Training or instructions regarding the proper care and use of suitable safety equipment in accordance with

the latest state of the art standards of safety technology.

- First aid training.

4 Electric Connection

Electric connections for the GTH 2448 / …are located at the back of the device.

Connection is made via screw-type/plug-in terminals (max. terminal range 1,5mm²).

Make it a rule to always mount screw-type/plug-in terminals while they are still loose and connect only later.

If terminals are mounted after connection there is a risk that soldering eyes may come loose. Please use

suitable screw-driver and do not tighten screws by force.

Supply voltage: 12 V DC or 24 V DC

Please make sure to check if supply voltage and

voltage range set conform to each other. Use the

soldering jumper next to the connection terminal

to select supply voltage.

Jumper "A1" open: 24 V (18 - 29 V DC)

Jumper "A1" closed: 12 V (8 - 20 V DC)

Probe connection:

GTH 2448 / 2, / 3: Pt100, 2-wire

GTH 2448 / 4, / 5: Pt1000, 2-wire

Both the connection and commissioning of the device must only be carried out by skilled personnel.

In case of a wrong connection, the device may be destroyed - no warranty claims can be accepted!
