    (Decimal Place): defines 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 information.
  • Page 12 Battery or RST Battery options. The Internal Battery option is used to monitor the voltage of a battery powered MND. The RST Battery option is used to monitor the supply voltage of an RST-5000 module acting as the master device.
  • Page 13 (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.

  • Page 16 (in seconds). NOTE: when using the Timed Interval in conjunction with the Auto-Off feature, the MND will wake (power on) at each Interval and will remain powered on for the duration of the relay On-Time regardless of the Auto-Off setting.
  • Page 17 Switchable Power Source Output Option* (refer to Switchable Power wiring on pages 4-5) This option is designed to allow an internal battery powered MND to share its battery power (via relay T1) with one of APG’s Modbus sensors (MNU, MPX, or PT series) to create a simple yet complete monitoring system.
  • Page 18 (acting as the master device). SETUP : sets the MND to act operate as a “slave” device in order to be programmed using the APG Modbus software. NOTE: the Sensor Address parameter (see below) is used to set the MND’s own sensor address when operating in Setup mode.
  • Page 19 Rev. A, 6/15 NUMSEN (Number of Sensors): sets the number of sensors to be monitored. When using the MND to display readings from multiple sensors, the sensor addresses must begin at 1 and increment sequentially (see note above). REGNUM (Register Number): sets the register number to be displayed. The readings of APG sensors are stored in register 30303.
  • Page 20 Rev. A, 6/15 WRITE : allows the MND, operating in Master mode, to write a value to a specific holding register of a specific sensor. When Write is selected, the MND will guide you through the following steps: Sensor Address: set the address number of the target sensor.
  • Page 21 Percent Full mode. NOTE: when controlling one of the MND’s outputs with a sensor setup to display in Percent Full mode, the settings controlling the output need to be entered based on the underlying readings and not the displayed percentage value.
  • Page 22 The software used to program the MND is the same software used to program any of APG’s line of Modbus sensors (MNU, MPX, PT series). Interfacing with the software also allows the user to save MND configurations to a PC, or to write a previously saved configuration back to the MND (see page 25).
