8. Options
8.1 Disconnectable audible over-temperature alarm (option)
This option permits activating an audible signal with the buzzer switch (10) (BD) resp. (9) (ED / FD).
Position 0 = buzzer off
Position 1 = buzzer active
If the buzzer is activated, an audible signal sounds when the limit temperature set at the temperature
safety device class 2 (chap. 7.1) or class 3.1 (chap. 7.2) is exceeded, this happens in addition to the red
alarm pilot lamp (7a) lighting up. The buzzer can be turned off using the buzzer switch (10) resp. (9).
Turning off the audible alarm does not influence the safety device’s regulatory or turning off
function. Proceed as described in chap. 7.1 / 7.2.
8.2 Communication software APT-COM™ 3 DataControlSystem (option for ED)
The chamber is regularly (BD) or optionally (ED) equipped with a serial interface RS 422 that can connect
the BINDER communication software APT-COM™ 3 DataControlSystem. The connection to a computer
is established using the unit interface via an interface converter RS 422 / RS 232.
The actual temperature values are given at adjustable intervals. Programming can be performed
graphically via PC. Up to 30 chambers with RS 422 interface can be cross linked. For further information,
refer to 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 drying and heating ovens ED (option) are to be recorded via a
PC, each one must be allocated a unique address. Addressing is performed via the chamber
controller (see chap. 6.4.3 ).
8.3 Data logger kit (option)
BINDER Data Logger Kits offer an independent long-term measuring system for temperature. They are
equipped with a keyboard and a large LCD display, alarm functions and a real-time function.
Measurement data are recorded in the Data Logger and can be read out after the measurement via the
RS232 interface of the Data Logger. It offers a programmable measuring interval and permits storing up
to 64000 measuring values. Reading out is done with the Data Logger evaluation software. You can give
out a combined alarm and status protocol directly to a serial printer.
For BD: Data Logger Kit T 220: Temperature range -90 °C / -130 °F up to +220 °C / 428 °F
For ED/FD: Data Logger Kit T 350: Temperature range 0 °C / 32 °F up to +350 °C / 662 °F
For detailed information on installation and operation of the BINDER Data Logger, please
refer to the mounting instructions Art. No. 7001-0204 and to the original user manual of the
manufacturer, supplied with the data logger.
