THERMASGARD® ATM 2
Calibratable outside temperature measuring transducer THERMASGARD® ATM 2 with eight switchable measuring ranges, external sensor, continuous output, housing made from impact-resistant plastic with quick-release screws, optionally with/without display, with cable gland or M12 connector according to DIN EN 61076-2-101. It is used to detect outside temperatures, and temperatures in wet rooms, e.g. for installation on outside walls, in cold storage buildings and greenhouses, in the industrial sector, and in agriculture.  Installation in outdoor areas preferably on the north side of a building or in a protected place. In the case of direct solar irradiation, we recommend the use of our sun and ball-impact protection hood WS 01 or WS 04 (accessories) or the device version with the installed sun protection hood SS 02 (on request). The sensor is factory-calibrated;  an environmental precision adjustment by an expert is possible.

Measuring transducers, calibratable, with active output
TEMPERATURE RANGES:
When selecting measuring transducer ranges, it is necessary to ensure that the maximum temperatures permissible for sensor/enclosure are not exceeded!
Ambient temperature for measuring transducers: – 30 …+ 70 °C
Apparent ohmic resistance = see load resistance diagram

SUPPLY VOLTAGE :
For operating voltage reverse polarity protection, a one-way rectifier or reverse polarity protection diode is integrated into this device variant. This internal one-way rectifier also allows operating 0 – 10 V devices on AC supply voltage.
The output signal is to be tapped by a measuring instrument. The output voltage is measured against zero potential (O V) of the input voltage!
When this device is operated on DC supply voltage, the operating voltage input UB+ is to be used for 15…36 V DC supply and UB – or GND for ground wire!

When several devices are supplied by one 24 V AC voltage supply, it is to be ensured that all ”positive“ operating voltage input terminals (+) of the field devices are connected with each other and all ”negative“ operating voltage input terminals (–) (= reference potential) are connected together (in-phase connection of field devices). All outputs of field devices must be referenced to the same potential!
In case of reversed polarity at one field device, a supply voltage short- circuit would be caused by that device. The consequential short-circuit current flowing through this field device may cause damage to it. Therefore, pay attention to correct wiring!

Installation and Commissioning

Devices are to be connected under dead-voltage conditions. Devices must only be connected to safety extra-low voltage. Consequential damages caused by a fault in this device are excluded from warranty or liability. These devices must be installed and commissioned by authorized specialists. The technical data and connecting conditions shown on the device labels and in the mounting and operating instructions delivered together with the device are exclusively valid. Deviations from the catalog representation are not explicitly mentioned and are possible in terms of technical progress and continuous improvement of our products. In case of any modifications made by the user, all warranty claims are forfeited. Operating this device close to other devices that do not comply with EMC directives may influence functionality. This device must not be used for monitoring applications, which serve the purpose of protecting persons against hazards or injury, or as an EMERGENCY STOP switch for systems or machinery, or for any other similar safety-relevant purposes.
Dimensions of housing or housing accessories may show slight tolerances on the specifications provided in these instructions.
Modifications of these records are not permitted.
In case of a complaint, only complete devices returned in original packing will be accepted.
Notes on commissioning:
This device was calibrated, adjusted, and tested under standardized conditions. When operating under deviating conditions, we recommend performing an initial manual adjustment on-site during commissioning and subsequently at regular intervals.
Notes regarding mechanical mounting and attachment:
Mounting shall take place while observing all relevant regulations and standards applicable for the place of measurement (e.g. such as welding instructions, etc.). Particularly the  following shall be regarded:

• VDE ⁄ VDI directive technical temperature measurements, measurement set-up for temperature measurements.
• The EMC directives must be adhered to.
• It is imperative to avoid parallel laying of current-carrying lines.
• We recommend using shielded cables with the shielding being attached at one side to the DDC ⁄ PLC.

Before mounting, make sure that the existing thermometer‘s technical parameters comply with the actual conditions at the place of utilization, in particular in respect of:

• Measuring range
• Permissible maximum pressure, flow velocity
• Oscillations, vibrations, and shocks are to be avoided (< 0.5 g)

CONNECTING CONDITIONS
Output: 0 – 10 V
The output voltage follows linear to the temperature signal applied at the input terminals and generates a proportional output signal of 0 – 10 V.
The voltage outputs are short-circuited proof against the ground wire. Applying voltage supply to the output terminals will destroy the device.
Output: 4 … 20 mA
In the case of the 4 … 20 mA measuring transducer, display, and evaluating elements are connected in series in the current loop. The measuring transducer thereby limits the flowing current in the variance of the input signal. 4 mA are for the measuring transducer‘s internal current consumption. The apparent ohmic resistance can either be connected in the plus or minus path of the measuring transducer. In case of an apparent ohmic resistance in the plus path, power supply and resist.

SAFETY REGULATIONS
These devices shall only be used for their intended purpose. Respective safety regulations issued by the VDE, the states, their control authorities, the TÜV, and the local energy supply company must be observed. The buyer has to ensure adherence to the building and safety regulations and has to avoid all dangers of any kind. We do not assume any warranty for faults or damages arising or resulting from improper use of our equipment or from non-observance of operating instructions. These instruments must be installed by authorized specialists only!
Preferably shielded cables should be used in order to prevent damages ⁄errors. It is imperative to avoid laying parallel with current-carrying lines. EMC directives must be adhered to.
