MX32v2
ANALOG AND DIGITAL CONTROLLER
USER MANUAL
Revision D.0
• In normal operation mode and without any time delay that the user could have
programmed,
MX32v2
response time is less than 2 seconds regardless of the number of
inputs/outputs.
• Time delay and relay operation settings (see voir Alarm Thresholds and Relays, page
17) is the responsibility of the user.
• Over-range (flammable gases)
As soon as gas concentration exceeds 100% LEL,
MX32v2
stores the over-range
condition and displays
>100% LEL.
The concerned channel goes into alarm and fault
condition and OVS
(OVERSCALE)
and FAULT
(FAULT)
visual indicators are lit.
Alarm reset is manual and under the responsability of the user who must follow the
site-specific safety guidelines. Over-
range condition can only be deactivated by
switching off the detector via the maintenance menu providing the gas concentration
is below the alarm threshold.
•
MX32v2
controller must not be exposed to mechanical vibrations and must be installed
in a non-hazardous area.
• With respect to installation in explosive atmospheres, the electrical installation must
comply with the regulation in force, in particular EN 60079-14 and EN 6079-17
standards (current editions) and, if necessary, additional requirements of domestic or
national regulations that apply to the place of installation.
Connecting detectors other than
TELEDYNE OLDHAM SIMTRONICS
detectors to the
MX32v2
controller
Any user wishing to use detectors other than TELEDYNE OLDHAM SIMTRONICS detectors must
ensure that they are compatible with the controller, in order the complete installation to be
considered as a safety device.
13.3.1 Transfer table
The following table shows the controller status depending on the detector analog signal output.
In the event the user connects a non-
TELEDYNE OLDHAM SIMTRONICS
brand detector to the
MX32v2
controller, the user must ensure that the detector is compatible with the input
characteristics of the controller, so that the information delivered by the detector will be
properly interpreted. In addition, the controller must provide sufficient supply voltage, taking
into account voltage drops in the cable.
0 to 2.4 mA Fault
>2.4 to 21.6mA Measurement
>21.6 mA Over Range Fault
