7.6 ALARM sub-menu
This sub menu where the alarm functions can be set.
7.6.1 O/P (output) Alarm AL ARM
HIGH
This enables the 4-20 mA alarm function.
If the self-diagnostic electronics determine
that the sensor output has been constant for a
period of time, or is not giving out a signal, it
will set the 4-20 mA output to 22 mA.
OFF
This disables the 4-20 mA alarm function.
7.6.2 POWER ALARM
OFF
This disables the power alarm function. The power alarm indicates that the power
supply to the MVT10 has been interrupted at
some point.
ON
This enables the power alarm function.
7.6.3 SAt ALARM
On
Enables the Sub Saturation Alarm.
Off
Disables the Sub Saturation Alarm.
dELAy
This sets the time duration before alarm is displayed. Can be zero.
This allows the Sub Saturation Alarm to be enabled or disabled.
below saturation temperature.
7.6.4 COMMS ALARM
The comms alarm or communication alarm can be switched either ON or OFF.
Modbus communication errors can be caused by incompatible baud rates, incorrect parity settings or poor
cabling in noisy environments. MVT10 can detect when communications errors occur and alert the user
via the display. If the comms alarm is enabled and a communication error occurs “PAR ERROR” will be
displayed for 3 seconds.
