5.1.6 Alarm output
The controller is provided with an alarm output. See item (1) on the Connections diagram.
Warning
Only connect the alarm output to equipment that complies with EN 61010-1 or IEC 950 or their
equivalent.
The alarm output is provided for indication of control deviations and sensor failures. It must never
be used as the sole alarm or for safety critical applications.
Do not exceed the maximum rating of the relay output stated below.
The user must ensure that the equipment attached complies with all regulatory requirements.
All cabling should be fully screened and should not exceed 2m in length. Lengths > 2m may
require special provisions to prevent electrical inference affecting the performance of the system
or compromising the EMC compliance.
Connector required 3.5 mm Stereo jack. Planer part number CO009129
Relay output Normally closed, volt free contacts.
12 V AC or DC, 0.5 A maximum.
The relay is normally closed and is opened by the controller when an alarm condition is detected. If
the alarm occurs because of a power failure, the relay will only be open during the backup period;
see
Power backup . As such, it is advisable to connect the alarm output to equipment that can
latch the alarm state.
5.2 Decontaminating the system
In most situations, chemical disinfection will be the most appropriate form of decontamination. The
procedure below is based upon using MedDis, a broad spectrum disinfectant manufactured by
MediChem International. However the final choice of disinfectant to be used must be made at a local
level based upon an assessment of the hazards to be dealt with.
Warning
Note that disinfectants are potentially hazardous to health. Ensure that you obtain a material
safety data sheet (MSDS) before use and follow the instructions contained therein.
Bleaches are corrosive and may damage sensitive components and metal surfaces within the
chamber.
The person responsible for the laboratory safety should prepare standard operating procedures
(SOPs) for the equipment, appropriate to the materials to be processed within the chamber; the
instructions below are provided to assist with the formulation of the SOPs. Decontamination is not a
routine procedure and should only be carried out if the system has been in contact with blood, other
body fluids, respired gases, pathological samples or hazardous substances. The system is not
