1 Safety notes

Safe and secure operation of the head transmitter can only be guaranteed if the operating

instructions and all safety notes are read, understood and followed.

1.1 Designated use

• The unit is a universal, presettable temperature head transmitter for resistance temperature

detectors (RTD), thermocouple (TC) as well as resistance and voltage sensors. The unit is

constructed for mounting in a connection head (DIN form B) or field housing.

• The manufacturer cannot be held responsible for damage caused by misuse of the unit.

• Separate Ex documentation is part of this operating manual, for measurement systems in

hazardous areas. The installation conditions and connection values indicated in these instructions

must be followed!

1.2 Installation, commissioning and operation

The unit is constructed using the most up-to-date production equipment and complies to the safety

requirements of the local guidelines. The temperature transmitter is fully factory tested according to

the specifications indicated on the order. However, if it is installed incorrectly or is misused, certain

application dangers can occur. Installation, wiring and maintenance of the unit must only be done

by trained, skilled personnel who are authorized to do so by the plant operator. This skilled staff

must have read and understood these instructions and must follow them to the letter. The plant

operator must make sure that the measurement system has been correctly wired to the connection

schematics.

Electrical temperature sensors such as RTD's and thermocouples produce low-level signals

proportional to their sensed temperature. The temperature transmitter converts the low-level sensor

signal to a standard 4 to 20 mA DC signal that is relatively insensitive to lead length and electrical

noise. This current signal is then transmitted to the control room via two wires.

The transmitter needs to be commissioned before installation in a hazardous area. Configuration of

the device in explosion area is not allowed. Make sure the instruments in the loop are installed in

accordance with intrinsically safe or non-incendive field wiring practices before connecting in an

explosive atmosphere.

The transmitter electronics module is permanently sealed within the housing, resisting moisture and

corrosive damage. Verify that the operating atmosphere of the transmitter is consistent with the

appropriate hazardous locations certifications.

#Warning!

Electrical shock could cause death or serious injury. If the sensor is installed in a high voltage

environment and a fault or installation error occurs, high voltage may be present on the transmitter

leads and terminals.

Temperature Effects

The transmitter will operate within specifications for ambient temperatures between -40 and 185 °F

(-40 and 85 °C). Heat from the process is transferred from the thermowell to the transmitter

housing. If the expected process temperature is near or beyond specification limits, consider the use

of additional thermowell lagging, and extension nipple, or a remote mounting configuration to

isolate the transmitter from the process.
