9.2 Communication software APT-COM

3 DataControlSystem (BD, option ED)

The oven is regularly equipped with a serial interface RS 422 to which the BINDER communication

software APT-COM

3 DataControlSystem can be connected. The connection to a computer is

established using the unit interface via an interface converter RS 422 / RS 232.

In adjustable intervals the actual temperature, and fan speed values are put out. Programming can be

performed graphically via PC. Up to 30 chambers with RS 422 interface can be cross linked. Further

information can be obtained in the operating manual of the BINDER communication software APT-COM.

Pin allocation of the RS 422 interface:

pin 2: RxD (+)

pin 3: TxD (+)

pin 4: RxD (-)

pin 5: TxD (-)

pin 7: Ground

If several incubators BD or heating/drying ovens ED (option) are to be recorded via a PC,

each one must be allocated a unique address. Addressing is performed via the R3 controller

(see chapter 7.4.3 ).

9.3 Analog output for temperature (option)

With this option the chamber is equipped with an analog output 4-20 mA for temperature. This output

allows transmitting data to external data registration systems or devices.

The connection is carried out as a DIN socket at the rear side of the chamber as following:

ANALOG OUTPUT 4-20 mA DC

PIN 1: temperature –

PIN 2: temperature +

Temperature range:

BD: 0°C to +100°C

ED, FD: 0°C to +300°C

A suitable DIN plug is enclosed.

9.4 Additional Pt100 temperature sensor (option BD)

An additional fixed or flexible temperature sensor Pt100 allows measuring the chamber temperature

(fixed Pt100) or the temperature of the charging material (flexible Pt100) by means of an independent

measuring system with Pt100 entry. The sensor top protective tube of the flexible Pt100 can be immersed

into liquid substances.

Technical data of thePt100 sensor:

• Three-wire technique

• Class B (DIN EN 60751)

• Temperature range up to 320°C

• Stainless steel protective tube 45 mm length

material no. 1.4501
