The BioFlo 4500 also has provision to allow the connection of an external alarm
device. An external alarm device is connected to the console via the nine-pin
ALARM CONNECTOR
on the rear panel ( see drawing above ). A cable must be
fabricated in order to use this option. Refer to Appendix A of this manual for the
correct pin locations on the connector.
The external alarm output is made up of two alarm contacts. The contacts are
normally open (NO) or normally closed (NC) relay contacts. The alarm will
either close or open the relay contact, depending on which type is applied, when
an alarm condition occurs. When the alarm is either disabled or acknowledged,
the controller will return the relay contact to its original position.
4.5 BioCommand Connections
A 25-pin
BIOCOMMAND COM PORT
is provided on the rear panel to connect the
BioFlo 4500 to an optional BioCommand interface box that allows communication
to a supervisory host computer. Communications to BioCommand software are
accomplished through an optional
RS-232 INTERFACE CABLE
.
Connect the 25-pin end of the
RS-232 INTERFACE CABLE
to the
BIOCOMMAND
PORT
, ensure that the connection is secure, and hand tighten the thumbscrews.
Refer to the BioCommand User’s Guide for instructions on connecting the
RS-232
INTERFACE CABLE
