Object Temperature Display With Flexible Pt 100 Temperature Sensor (Option); Connection Of The Object Temperature Sensor - Binder VDL Series Operating Manual

Connections at the measuring access port
• At the inner side of the measuring access port you can solder up to 9 cables. The inside connections
must be insulated against each other and against ground. Use 300 °C / 572 °F solder.
• The 9 contacts are conducted outside via the measuring access port. You can use them to connect a
device via the delivered plug.
Maximum load capacity of the switching contacts: 42 V AC/DC - 2A
Electrical hazard due to exceeding the load capacity of the switching contacts.
Damage to switching contacts and connection socket. Deadly electric shock.
∅ Do NOT exceed the maximum switching load of 42 AC/DC – 2Amp.
∅ Do NOT connect any devices with a higher load capacity.
 Insulate the inside connections against each other and against ground. Use 300 °C /
572 °F solder.

25.4 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 mate-
rial. This enables the determination of the actual temperature of the charging material during the whole
process. The object temperature is measured via a flexible Pt100 sensor inside the inner chamber and
can be viewed on the controller display. 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 connection cable is firmly connected to the connection "Object temperature input" (3a) located in the
VDL rear control panel. The connection is realized as a 9-poles SUB-D socket

25.4.1 Connection of the object temperature sensor

• Insert the Pt 100 temperature sensor from the rear through the measuring connection (12) 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 9-poles SUB-D socket "Object temperature input" of the connection
(3a). For reasons of explosion protection, this electrical connection to the inner chamber is conducted
via a triple internal safety barrier with a conducting-state voltage of 1.6 Volt maximum against ground.
• Connect the supplied cable to the measuring access port and into SUB-D-socket of the connection
(3a).
