1 General
1.1 Safety Requirements
This device has been designed and tested in accordance with the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures
and special safety advises given in this manual will be adhered to when using the device.
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".
2. Device and sensors have to be handled with care (don’t throw, hit, etc.). Protect plugs and sockets from
soiling.
3. 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.
4. If device is to be connected to other devices (e.g. via serial interface) the circuitry has to be designed
most carefully. Internal connection in third party devices (e.g. connection GND and earth) may result in
not-permissible voltages impairing or destroying the device or another device connected.
Warning:
If device is operated with a defective mains power supply (e.g. short circuit from mains voltage
to output voltage) this may result in hazardous voltages at the device (e.g. at sensor socket or interface).
5. 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 period of time.
In case of doubt, please return device to manufacturer for repair or maintenance.
6.
Warning:
Do not use these product as safety or emergency stop device, 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.
1.2 Operation And Maintenance Advice
•
Battery Operation
If ´bAt´ is shown in the secondary display the battery has been used up and needs to be replaced. The
device will, however, operate correctly for a certain amount of time. If ´bAt´ is shown in the upper display
the voltage is too low to operate the device; the battery has been completely used up.
Please note: The battery has to be taken out, when storing device above 50°C.
We recommend to take out battery if device is not used for a longer period of time!
The real time clock has to be set again after reconnect to the battery.
•
Mains Operation With Power Supply
Warning:
When using a power supply please note that operating voltage has to be 10.5 to 12 V DC.
Do not apply overvoltage!! Cheap 12V-power supplies often have excessive no-load voltage.
We, therefore, recommend using regulated voltage power supplies. Trouble-free operation is guaranteed
by our power supply GNG10/3000.
Prior to connecting the power supply to the mains make sure that the operating voltage stated at the
power supply is identical to the mains voltage.
!
Connecting/Changing Sensors
Do not use insuitable sensors. Connecting other devices/sensors as specificated may cause a damage to
the instrument and device/sensor! Switch off device before changing the sensor.
Connect sensors before switching on the device, otherwise the sensor may not be detected correctly.
When connecting the sensor the connector may not lock correctly. In such case take the plug not at the
casing but at the buckling protection at the end of the plug. If plug is entered correctly, it will slide in
smoothly. To disconnect sensors do not pull at the cable but at the plug (to open locking mechanism).
