High Flow Alarm
If any system alarm is enabled and the flow for that respective system’s fan exceeds the individual fan
high flow alarm value set in the Setup Menu Section 5.2.7 Alarms, then a High Flow Alarm will occur.
Low Flow Alarm
If any system alarm is enabled and the flow for that respective system’s fan falls below the individual
fan low flow alarm value set in the Setup Menu Section 5.2.7 Alarms, then a Low Flow Alarm will occur.
Differential Pressure Alarm
If any
Δ
P alarm is enabled and the pressure for that respective
Δ
P exceeds or falls below the set alarm
value (dependent on
Δ
P alarm trigger type being high or low set in the Setup Menu Section 5.2.9) then
a Differential Pressure Alarm will occur.
Sensor Acknowledge Error
If any one of the sensors that are present in the MTSE loses communication with the host MCU, then a
Sensor Acknowledge Error will occur.
Analog Output Error
If any of the four analog outputs are short circuited while set to voltage, open circuit while set to mA, or
the circuit is overloaded, an Analog Output Error alarm will occur. Analog output error will be displayed
if the process output is set to 4-20mA and there is no receiving device connected (this is an open
circuit).
Flow Exceeds Operating Range
If the measured flow value exceeds the entered Operating Range value for any system, a Flow
Exceeds Operating Range alarm will occur. The MTSE will continue to read and display values above
the operating range however the operating range sets the process output scale and therefore the
output will be saturated at 20mA or 10V.
Firmware Update
During the bootup sequence of the MTSE the host MCU will check its firmware against the firmware
present on the uSD card. If the uSD card has newer firmware available this message and button will
appear.
