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 APT-COM™ 4 Multi Management Software (option for BD and ED)
The chamber is regularly (BD) or optionally (ED) equipped with a serial interface RS 422 that can connect
the BINDER APT-COM™ 4 Multi Management Software. The connection to a computer is established using
the chamber’s 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 100 chambers can be cross linked. For further information, refer to the APT-COM™ 4
operating manual.
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 Additional Pt100 temperature sensor (option for BD)
An additional fixed or flexible temperature sensor Pt100 permits 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 / 608 °F
•
Stainless steel protective tube 45 mm length
material no. 1.4501
