LIMITED WARRANTY

The manufacturer offers the customer a 24-month functional warranty on the instrument for faulty workmanship or parts from date of dispatch from the distributor. In all cases, this warranty is valid for 36 months from the date of production. This warranty is on a return to factory basis.

This warranty is only applicable to Multi-Mon instruments using Multi-Mon current transformers.

The manufacturer does not accept liability for any damage caused by instrument malfunction. The manufacturer accepts no responsibility for the suitability of the instrument to the application for which it was purchased.

Failure to install, set up or operate the instrument according to the instructions herein will void the warranty.

Only a duly authorized representative of the manufacturer may open your instrument. The unit should only be opened in a fully anti-static environment. Failure to do so may damage the electronic components and will void the warranty.

The greatest care has been taken to manufacture and calibrate your instrument. However, these instructions do not cover all possible contingencies that may arise during installation, operation or maintenance, and all details and variations of this equipment are not covered by these instructions.

For additional information regarding installation, operation or maintenance of this instrument, contact the manufacturer or your local representative or distributor.

Safety Requirements

Safety ReqSafety Req

To ensure safety requirements the Multi-Mon must be grounded - the protective ground terminal should be connected to protective earth with a copper conductor or strap with minimal length (less than 1 m desirable) and cross-section 5.3 mm

The properly marked external 3-pole disconnect device with circuit-breaker and a fuse 6A, 600V in every pole should be installed between voltage measurement terminals and power lines, located as close as possible (less than 2 m recommended) to the Multi-Mon, as shown in figure 2-5 .

The flashing yellow CPU LED shows that the device is operational and is

functioning normally.

The green TX and RX LEDs indicate activity on the COM1 communication port. The LEDs flash when the port is receiving or transmitting data.

The red “Wh” LED flashes at a user-programmed rate when a load is applied to the device. In normal mode, the LED pulses indicate imported Wh for a selected submeter. In energy test mode, the LED pulses indicate either imported Wh, or imported (inductive) varh for a selected submeter. Energy test mode is used for testing the device energy measurement accuracy. In test mode, the energy and demand accumulators do not account for consumed energy.

See Device Options in Chapter 3 and General Meter Setup in Chapter 4 on how to put the device into energy test mode and how to select the LED pulse rate and a submeter for testing.

The Multi-Mon is provided with an LCD display and four push buttons that are used for local meter reading and setup. See Multi-Mon Display

Operations in Chapter 3 for information on using the front panel display.

Device Settings

Before operating your Multi-Mon, provide the device with information about your particular environment. The device front display (see Display

Operations (Multi-Mon)) and the supplementary Power Software (see Power Software Application Software) allow you to configure the Multi-Mon for your

particular use.

The Multi-Mon configuration setups are secured by a factory-preset password. Contact your dealer for your primary password. Later, you will be able to change the password via the device Access Menu (see Meter

Security).

The Multi-Mon provides up to 36 submeters with separate measurement and energy registers. Each submeter can service current inputs dedicated to a particular consumer (metering submeter) or be used as a totalization meter for automatic totalization of energy from different sub-consumers (totalization submeter). Additionally, the Multi-Mon provides four more totalization submeters (37 through 40) that you can use for totalization purposes when all 36 metering submeters have been utilized.

A submeter remains inactive while there are no current inputs associated with the submeter (see Channel Assignments), or until you link another submeter as a source to its energy registers making it a totalization submeter (see Setting up Total and Tariff Registers). The Channel Assignment setup allows you to link one to three current inputs to each submeter and to specify the primary rating of the current transformers. A totalization submeter provides totalization of energy from any number of metering and totalization submeters.

By default, your device is configured for 12 three-phase metering submeters with 100A (maximum) current inputs (50A nominal rating).

Addressing Addressing

The Multi-Mon uses the Modbus communication protocol for data transmission and accessing setups through communications. A full description of the communications protocol is found in the Multi-Mon Modbus Reference Guide provided with your device.

Each active submeter in the Multi-Mon is assigned a unique communication address that allows accessing its private registers and setups. All submeter addresses are assigned automatically in a sequential order starting with the device base address that is programmed through the device Communication Setup (see Setting Up Communication Ports ). The following table illustrates submeter addressing in the device with the base address N.

Select your submeters (both metering and totalization) in a sequence without gaps so that your device does not occupy unnecessary network addresses.

If you connect a number of devices to a serial network, allocate a range of addresses for each device so that they do not overlap. For example, if you use three devices with 12 submeters in each one, assign the base address 1 to the first device, the address 13 to the second, and the address 25 to the third device so that they will occupy three non-overlapped address ranges 1 through12, 13 through 24, and 25 through 36.

For proper device operation, select the correct power frequency (see Basic

Device Settings) and set the correct primary ratings for device current inputs

(see Channel Assignments) before you connect the device to your network.

The Multi-Mon provides 4 separate billing energy (total/summary and parallel tariff and maximum demand) registers for each individual submeter. Each register can be linked to any internal energy source or another submeter. The first billing register in your meter is linked to the kWh accumulator by default. Other registers are not operational unless you configure them through the Energy/TOU Setup (see Configuring Billing

Energy and TOU Registers).

Device Diagnostics

Device DiagnosticsDevice Diagnostics

Device diagnostic messages may appear as a result of the Multi-Mon built-in diagnostic tests performed during start-up and device operation. See Device

Diagnostic Codes in Appendix F for the list of diagnostic codes and their

meanings.

The device diagnostics status is stored in a non-volatile register, which may be inspected and cleared via Power Software, from the meter display or from a user application. All diagnostic events with time stamps are also recorded in the device Event log and can be inspected via Power Software (see

Retrieving the Event Log in Chapter 4).

See Diagnostics Display and Reset in Chapter 3 on how to inspect and clear the device diagnostics status from the display. See Viewing and Clearing

Device Diagnostics in Chapter 4 on how to inspect and clear the device

diagnostics status via Power Software. Refer to the Multi-Mon Modbus Reference Guide for the diagnostic register address and layout.

In the event of a device fault, check the fault reason and clear the device diagnostics. In the event of a time fault, update the device clock. In the event of a configuration reset, check the setup affected by the fault via the device Event log, and then verify the setup data.

Hardware failures are normally non-critical recoverable faults that do not cause a system failure but may cause data loss. Hardware failures are often caused by excessive electrical noise in the region of the device.

If the device continuously resets itself, contact your local distributor.
