EXTENDED DETAILS |
ALARMS
Once an alarm is activated at the
transmitter it will display which input is in
alarm and the sounder will be activated. The
AS200RX receiver will display both the unit
number and input of the transmitter alarming;
these details will be time and date stamped. Any
communications equipment attached to the
receiver will be activated immediately or after
a programmable window of 10 minutes.
The system has a reactivation
circuit which will re-alarm at the receiver
after 1 hour if the transmitter in alarm has not
been muted. This stops alarms being ignored as
the user must mute the transmitter at the
equipment end. The reactivation facility can be
disabled or enabled at the receiver.
TEMPERATURE RANGE
The temperature range of the
transmitter is –200°C to +100°C with an accuracy
of 0.1°C across the entire range. This makes
the transmitter suitable for many types of
equipment from LN2 to incubators.
FRONT PANEL DISPLAY
The front panel display can be
used to show the unit number of the transmitter
or time delay or temperature of input 1. When
in an alarm condition the display toggles
between alarm I/P and variable selected. The
status led indicates the current condition of
the transmitter and the alarm active led flashes
brightly in an alarm condition.
HIGH & LOW ALARMS
A single high and low alarm can
be set for I/P1 and I/P2, these parameters can
easily be displayed.
DELAY TIME
A single delay time can be set
for I/P 1 and I/P 2 ranging from 0 to 90
minutes, these parameters can easily be
displayed. Input 3 has a fixed delay time of 10
minutes.
INPUTS
Up to three inputs are available
on the transmitter. A common configuration
would be to use input 1 to monitor the air
temperature of the equipment, input 2 to monitor
the sample temperature and input 3 to monitor
the door open / closed condition. This
configuration of the inputs will give maximum
protection and temperature data for the sample
will be recorded as well as the air temperature
if logging is employed on the system.
Input 1 : This is for
temperature and the value can be displayed on
the transmitter. This input sends its
temperature value to the receiver so it can be
monitored and logged if required.
Input 2 : This is for
temperature. This input sends its
temperature value to the receiver so it can be
monitored and logged if required. (This input is
an option)
Input 3 : This is a volt
free contact, normally closed in the OK
condition and normally open in the alarm
condition.
POWER FAILURE ALARM
If power failure is detected for
longer than 10 minutes the transmitter will
activate a power failure alarm at the
transmitter and receiver.
CALIBRATION
The temperature transmitter has
been designed to have an easy calibration
procedure. The transmitter display will show a
calibration reminder automatically which is
customer enabled, the reminder can be set for
intervals of 6 or 12 months or be disabled.
Traceable calibration for temperature can be
carried out for the AS200TX alarm transmitters.
AS200TS ► TEST TEMPERATURE FOB
Test temperatures at +50.0°C,
0.0°C and -50.0°C can be simulated on the
transmitter input 1 to test the alarm. The fob
temperature simulator is attached to a connector
inside the transmitter unit and a temperature
probe bypass switch is thrown. The
simulated temperature is selected and will be
shown on the display. If this temperature is
out with the alarm limits it will activate the
relevant alarm after the time delay.
DATA LOGGING & MONITORING
Data logging and
monitoring from AS200TX transmitters is possible
with the AS200RX receiver when used in
conjunction with a computer and relevant
software.
The data
collected for each transmitter is as follows :-
Serial Number, Unit Number, Temperature I/P1,
Temperature I/P2, High Alarm, Low Alarm and
Delay Time.
The transmitter will update the
computer every 30 minutes with the data. This
increases to every 10 minutes when the
transmitter is in an alarm condition. Faster
data collection
n available on request.
Data capture
software enables the display of variables
collected. A range of software is
available to cover clients requirements
including :-
· Trend
Graphs
· Multi-graphs
· Printed
Reports
· Recipe
& Batch Facility
· SMS
& Email Facilities
· FDA
21 CFR 11 Compliance
· Electronic
Records
and Signatures
