15.5 Measuring access port vacuum 9 poles (option)

The measuring access port allows creating electrical connec-
tions for low voltages or sensors between the exterior and inte-
rior of the VDL vacuum drying oven. A 9 poles plug for the out-
side is included.
with measuring access port and supplied plug
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 supplied plug.
Maximum load capacity of the switching contacts: 42 V AC/DC - 2A
Electrical hazard.
Danger of death.
Damage to switching contacts and connection socket.
∅ Do NOT exceed the maximum switching load of 42 AC/DC – 2 Amp.
∅ 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.
15.6 Communication software APT-COM™ 3 DataControlSystem (option)
The chamber is regularly equipped with a serial interface RS 422 (9) that can connect the BINDER com-
munication software APT-COM™ 3 DataControlSystem. The actual temperature value is given at adjust-
able intervals. Programming can be performed graphically via PC. Up to 30 chambers with RS 422 inter-
face can be cross-linked. For further information, refer to the operating manual of the BINDER communi-
cation software APT-COM™ 3.
Confirm that the interface mode is correctly set to "Modbus" in the user level (chap. 10).
