Then select the menu point “RS - 232” with the selection knob and set the setting “Remote” to “Off.
16.5 Digital pressure display (option)
With this option, a digital display indicates the internal pressure with the accuracy of 1 mbar / 0.03 inHg.
The pressure is measured by a permanently fitted internal pressure sensor.
A service engineer can calibrate and internally adjust the digital pressure display.

16.6 Additional measuring channel for digital object temperature display with
flexible Pt 100 temperature sensor (option)
The object temperature display permits recording the object temperature directly on or in the drying
material. The object temperature is measured via a flexible Pt100 sensor inside the inner chamber. The
sensor needs to be in thermally conducting contact with the charging material. It can be plunged into
humid charging material up to the length of its protecting tube.
The object temperature is indicated on Display 2 of the RD3 controller.

The object temperature data is put out combined with the temperature data of the temperature controller
to the RS 422 interface as a second measuring channel. This permits recording by the BINDER
documentation software APT-COM™ DataControlSystem (option, chap. 16.8).
Assembly and connection of the object temperature recording
• Insert the Pt 100 temperature sensor from the rear through the measuring connection (17) into the
inner chamber.
• The 3 contacts of the Pt 100 sensor are conducted outside via a measuring access port. From there,
establish the connection to the DIN socket at the top of the rear panel of the chamber marked “Pt100”.
