OUTPUT
(Outputs)
The MND is offered with optional outputs, such as solid-state relays, or 4-20 mA
or 0-3 Vdc analog signals. Not all output menu options are applicable to all MND
configurations.
NOTE: when displaying the readings from multiple sensors, the Sensor Address setting
determines which sensor is controlling the output(s) of the MND.
AL SET
(Analog Low Set-point): sets the reading associated with the low analog
value (either 4mA or 0V).
AH SET
(Analog High Set-point): sets the reading associated with the high analog
value (either 20mA or 3V).
AL CAL
(Analog Low Calibration): adjusts the low end of the analog output (either
4mA or 0V). Increasing/decreasing the value will cause an increase/decrease at the low
end of the analog output.
AH CAL
(Analog High Calibration): adjusts the high end of the analog output (i.e.
either 20mA or 3V). Increasing/decreasing the value will cause an increase/decrease at
the high end of the analog output.
T1TYPE
&
T2TYPE
(Trip 1&2 Type): determines the basic functional logic of the
relay outputs as described in the Trip Type descriptions on pages 14-16.
NOTE: the MND’s Telecom Relays are rated for a maximum switched load of 5 Amps at
240 VAC or 220 VDC.
T1REAd
&
T2REAd
(Trip 1&2 Reading): defines the display reading that
corresponds to a change in the state of the associated relay output, as determined by
the Trip Type selected.
T1 WIN
&
T2 WIN
(Trip 1&2 Window): defines the secondary value (beginning
from the Trip Reading) for Exclusive, Inclusive, and Hysteresis Near & Far Trip Types
(refer to descriptions below). For example: if the Trip Reading is set to 250, and the
secondary trip value is desired at a reading of 350, then the Trip Window should be set
to 100. (250 + 100 = 350)
