AUTO (Auto Off ): The Auto-Off feature will automa cally power off the MND whenever

no bu ons are pressed within the specifi ed  me frame. The minimum Auto-Off  me is

15 seconds. To disable the Auto-Off feature, set the value to 65535 (default).

NOTE: the Auto-Off cannot be set to less than the relay “On Time” se ng when using

the Timed Relay op on (see Outputs).

dEC PL (Decimal Place): defi nes where the decimal point will be displayed within the

reading.

NOTE: most APG sensors have the ability to set the number of decimal places of the

readings being sent to the MND. Refer to the sensor manual for more informa on.

MASK (Digit Mask): allows the user to mask the value of the least signifi cant digit(s), up

to 3 places, so that masked digit(s) will always display 0 and will not increment.

SHIFT (Digit Shi ): allows the user to shi the reading to the right by dividing the

reading by 10, 100, or 1000.

MLTPLR (Mul plier): allows the user to apply a conversion mul plier to the sensor

readings. For example, a mul plier se ng of 2.0 will double the reading received from

the sensor.

NOTE: most APG sensors have the capability to apply a conversion mul plier to the

reading before the value it is sent to the MND.

bAR 0 (Bar Graph 0%) & bAR100 (Bar Graph 100%): defi ne the readings associated

with 0% and 100% on the display bar graph. Bars will appear/disappear in 10%

increments of the total span.

LOERST

(LOE/RST):
forces the output to follow the state of the corresponding output of an LOE or RST
sensor ac ng as the master device. For example, whenever output T1 of the LOE/RST
ac vates/deac vates, then output T1 of the MND will ac vate/deac vate as well.

TIME R (Timed Interval):

sets the output to ac vate on a  med interval. The Interval-Time (
 me between ac va ons (in minutes), and the On-Time (

ON SEC) determines how

long the output remains ac ve at each interval (in seconds).

NOTE: when using the Timed Interval in conjunc on with the Auto-Off feature, the
MND will wake (power on) at each Interval and will remain powered on for the
dura on of the relay On-Time regardless of the Auto-Off se ng.

MND Rev . A1, 5/14

Switched Power Source

This op on is designed to allow an internal ba ery powered MND to share the ba ery
power with one of APG’s Modbus sensors (MNU, MP, or MPT series) to create a simple
yet complete monitoring system. Whenever relay 1 (T1) is ac ve, the ba ery voltage
will be applied to the switched power source output (which should be connected to the
voltage input of the sensor). By se ng relay 1 to “On” and then se ng up a short Auto-
Off  mer (refer to Advanced se ngs), the user can simply push the power bu on on
the MND to wake the system and poll the sensor to get the reading. The Auto-Off will
automa cally power down the system to save ba ery life. APG recommends an Auto-
Off se ng of 15-20 second in order to maximize ba ery life.

WARNING! the switched power output sources voltage directly from the ba ery, and
cau on must be taken not to let the output come in contact with any of the other
output lines (DC common or the communica on lines).

APG sensors are stored in register 30303.

NOTE: the register number is entered using only the last 3 digits of the full register

number. For example, register 30303 would be entered as 303, or register 40401

would be entered as 401.

FUNCTN (Func on): sets the func on code for the register to be displayed; 3 = holding

resister, 4 = input register. Sensor readings are stored in input registers, while sensor

parameter values are stored in holding registers.

REGTYP (Register Type): sets the bit type of the register to be displayed. Op ons are:

signed, 8 bit, low byte (S8L) signed, 16 bit (S16)

signed, 8 bit, high byte (S8H) unsigned, 16 bit (U16)

unsigned, 8 bit, low byte (U8L) signed, 32 bit (S32)

unsigned, 8 bit, high byte (U8H) unsigned, 32 bit (U32)

NOTE: the readings of APG’s sensors are stored as an unsigned 32-bit value. Refer

to the sensor’s user manual for a list of register numbers and their corresponding

register types.

SCANRT (Scan Rate): determines how o en the MND polls the sensor(s) (in seconds)

when opera ng in Master mode.

Allows sensor readings to be displayed as a percentage of full based on a user defi ned

100% value.

To enable the Percent Full feature, select

number you want to display as a percentage of full, and enter the value associated with

100%. 0% (empty) is assumed to be 0. Se ng the value to 00000 (default) will disable

• *INPUT (Analog Input) *Op onal Feature

Used to adjust how the MND reads the analog input signal.

SAM RT: determines how o en the MND reads the analog input signal.

AVERGE: determines how many readings of the analog signal will be averaged together

to become the displayed reading. A higher average se ng will result in smoother
readings but will also cause slower response to rapid changes.

The following is a list of parameters required to read an analog input:

COMM menu:
Set C-TYPE to AINPUT.

OUTPUT menu:
Set AL SET to the value associated with a 4mA input signal.
Set AH SET to the value associated with a 20mA input signal.
*Adjust AL CAL and AH CAL as necessary.

Programming the MND using APG Modbus So ware

The MND’s “Setup” communica ons type (see C-TYPE on page 17) allows the MND to be

programmed using so ware instead of the bu ons on the display. The so ware used

to program the MND is the same so ware used to program any of APG’s line of Modbus

sensors (MNU, MP, PT series). Interfacing with the so ware also allows the user to save

MND confi gura ons to a PC, or to write a previously saved confi gura on back to the

MND (see page 24).

Use the following steps to establish communica ons and program the MND via the APG

Modbus so ware:

Step 1: Use the bu ons on the MND to enter the Communica ons menu and change the

Communica ons Type (C-TYPE) to “SETUP”.

Step 2: While s ll in the MND Communica ons menu, take note of the Sensor Address

(SENAdR) se ng. This se ng will become the MND’s address when communica ng to

the so ware.

Step 3: Install and run the APG Modbus so ware.

Step 4: Click on “Confi gure” in the top menu,

then select “Communica on” to bring up the

Communica on Confi gura on window.
