Intended Use
This CO-transmitter is designed for specific purposes and should be used by
the safety regulations for electronic devices. It is important to adhere to
the standard safety measures and special safety advice provided in the user
manual for trouble-free operation and reliability.
Operating Advice
- Avoid subjecting the device to climatic conditions outside the specified range. Condensation due to temperature changes may cause failure of the device’s function. Allow the device temperature to adjust to the ambient temperature before starting it up again.
- Observe general instructions and safety regulations for electric, light, and heavy current plants, including domestic safety regulations (e.g., VDE).
- If connecting the device to other devices (e.g., via PC), ensure careful circuitry design. Improper internal connections in third-party devices may result in voltages that can damage the device or other connected devices.
- If there is any risk involved in operating the device, switch it off immediately and mark it accordingly to prevent accidental restarting. In case of doubt, contact the manufacturer for repair or maintenance.
- Warning: This product should not be used as a safety or emergency stop device. Failure to comply with instructions could result in personal injury, material damage, or even death.
Disposal Instructions
The device should not be disposed of in regular domestic waste. Please send
the device directly to the manufacturer (sufficiently stamped) for appropriate
and environmentally sound disposal.
Product Usage Instructions
Installation
No specific installation instructions are provided in the user manual.

No specific dimension details are provided in the user manual.
Assignment of Elbow-Type Plug
The elbow-type plug of the transmitter has a 2-wire connection (mA) assigned
as follows:
- 1 = signal +

Check of Transmitter
To maintain the function of the transmitter, it is recommended to periodically
check it with test-gas. Follow the steps below:
Preparation:
- Screw the closed MiniFlo valve onto the bottle.
- Connect the tube of the test gas cap to the valve.
- Snap the test gas cap onto the transmitter.
Execution:
Keep the bottle upright and slowly open the valve until the ball in the flow
indicator shows 0.5 l/min (the lowest marking of the indicator).
FAQ
-
Q: Can the CO – CO-transmitter be used as a safety device?
A: No, this product should not be used as a safety or emergency stop device. -
Q: What should I do if there is visible damage to the device?
A: If there is visible damage to the device, it is recommended to switch it off immediately and contact the manufacturer for repair or maintenance. -
Q: How should I dispose of the device?
A: The device should not be disposed of in regular domestic waste. Please send the device directly to the manufacturer (sufficiently stamped) for appropriate and environmentally sound disposal.
Intended use
- The GT1-CO is a transmitter for measuring poisonous carbon monoxide gas up to a concentration of 300 ppm (0.03 vol %). The 4-20mA output is intended to be connected to suitable displays or apparatus. The gas is measured at the sensor inlet sideways (blue), assembly position: Inlet pointing downwards.
- The measuring gas feed is realised via diffusion, therefore low air movement can delay measuring. Because of the verification according to VDI2053, the transmitter is permitted for underground car parks etc.
Operating advice
- CO gas is slightly lighter than air (rel. density = 0.97).
- The suggested mounting level is 1.5 – 1.8m above the ground floor, sensor opening downwards.
Safety Requirements
This device has been designed and tested by the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special safety advice given in this manual are adhered to when using the device.
-
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 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. -
General instructions and safety regulations for electric, light and heavy current plants, including domestic safety regulations (e.g. VDE), have to be observed.
-
If the device is to be connected to other devices (e.g. via PC) 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.
-
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 restarting.
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 long time
In case of doubt, please return the device to the manufacturer for repair or maintenance.
-
Warning:
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.
Disposal instructions
- The device must not be disposed in the regular domestic waste.
- Send the device directly to us (sufficiently stamped), if it should be disposed of. We will dispose of the device appropriate and environmentally sound.
Installation
Dimensions
General elbow-type plug installation instructions
To mount the connection cable (3-, or 4-wire depending on the type of device)
the elbow-type plug screw has to be loosened and the coupling insert has to be
removed using a screwdriver at the position indicated (arrow). Pull out the
connection cable through the PG landing and connect to the loose coupling
insert as described in the wiring diagram. Replace the loose coupling insert
onto the pins at the transmitter housing and turn the cover cap with PG
landing in the direction desired till it snaps on (4 different starting
positions at 90° intervals).
Re-tighten the screw at the angle plug.

Check of Transmitter
To maintain the function of the transmitter, it should be checked with test- gas periodically. The transmitter will be connected to a specified test gas and the referring display is checked. Make sure that you can read the display during the test, or perform the test with the help of a second person.
- Necessary equipment:
- Test gas cap GT (GZ-01)
- Test gas bottle (GZ-02 – 30ppm CO, GZ-03 – 300ppm CO)
- Extraction valve MiniFlo for gas bottle (GZ-04)
- Preparation:
- Screw the closed MiniFlo valve on the bottle
- Connect the tube of the test gas cap to the valve
- Snap the test gas cap to the transmitter
- Execution:
- Keep the bottle upright, and open the valve slowly, until the ball in the flow indicator shows 0.5 l/min. (lowest marking of indicator)
- The display rises to a max. value within 1 minute and should be within ±2% of the test-gas concentration.
Note:
If there is a larger deviation, the transmitter can be adjusted, see
“Adjustment”.
Adjustment
- To adjust the transmitter output: Open the housing by unscrewing the 4 screws.
- A single potentiometer is situated at the circuit board.
- By this, the output slope of the transmitter can be changed.
- Equipment and preparation: Please refer to “Check of Transmitter”
Execution:
- Keep the bottle upright, and open the valve slowly, until the ball in the flow indicator shows 0.5 l/min. (lowest marking of indicator)
- The display rises to a max. value within 1 minute.
The adjustment should be performed quickly at the maximum value (best, if not longer than 30 seconds) – falling values afterwards should be ignored.
