2.1 Scope of delivery

The scope of delivery always consists of the transmitter and its documentation.

2.2 General description

TT 11 C

TT 11 CTT 11 C

The TT 11 C is an analogue multi-range 3-wire in-head transmitter for temperature measurements. It works together with measuring resistors of the types Pt100 and Pt1000. The device has an output with the range 0...10 VDC; the manufacturer has designed the transmitter especially for building services applications as HVAC systems often require a signal in the range of 0...10 V.

The in-head transmitter is intended for installation in a "B connection head" or larger according to DIN 43729. As an alternative you can also mount the in-head version on a rail according to DIN EN 50022 with the help of the rail mounting kit (further information on page 14).

DEVICE DESCRIPTION 2

TT 11 R

TT 11 RTT 11 R

The TT 11 R is an analogue 3-wire rail-mount transmitter for temperature measurements with the same features as the in-head version.

The rail-mount transmitter is intended for installation on a rail according to DIN 50022.

INFORMATION!

In the standard delivery condition the transmitters are not preset. Therefore you have to make a complete solder pad configuration before using the transmitter for the first time (refer to chapter "Operation"). As an option the manufacturer offers preset transmitters according to the customer's order.

3.1 Notes on installation

INFORMATION!

Inspect the cartons carefully for damage or signs of rough handling. Report damage to the carrier and to the local office of the manufacturer.

INFORMATION!

Check the packing list to check if you received completely all that you ordered.

INFORMATION!

Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate.

3.2 In-head transmitter

DANGER!

OPTITEMP TT 11 C/R

CAUTION!

The manufacturer has developed the in-head transmitter for an operating temperature range of

-40...+85 operating temperature does not exceed the permissible range. Also note that the thermowell transfers the process temperature to the transmitter housing. If the process temperature is close to or exceeds the maximum temperature of the transmitter, then the temperature in the transmitter housing can rise above the maximum permissible temperature!

One way to decrease the heat transfer via the thermowell is to install the transmitter farther away from the heat source. An alternative is to make the thermowell longer. Inversely you can take similar measures if the temperature is below the specified minimum temperature.

C / -40...+185°F. To avoid destruction or damage of the device, always assure that the
