• OUTPUT (Outputs)
The MND is off ered with op onal outputs, such as solid-state relays, or 4-20 mA
or 0-5 Vdc analog signals. Not all output menu op ons are applicable to all MND
confi gura ons.
NOTE: when displaying the readings from mul ple sensors, the Sensor Address se ng
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). Used for analog output or analog input.
AH SET
(Analog High Set-point): sets the reading associated with the high analog value
(either 20mA or 5V). Used for analog output or analog input.
AL CAL
(Analog Low Calibra on): 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 Calibra on): adjusts the high end of the analog output (i.e. either
20mA or 5V). 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 func onal logic of the solid-
state relay outputs as described in the Trip Type descrip ons on pages 14-16.
NOTE: the MND’s solid-state relays are rated for a maximum switched load of 120 mA.
T1REAd
&
T2REAd
(Trip 1&2 Reading): defi nes 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): defi nes the secondary value (beginning from
the Trip Reading) for Exclusive, Inclusive, and Hysteresis Near & Far Trip Types (refer to
descrip ons 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)
