3. OPERATION
3.1 General
The SDTA-01 is designed for interfacing alternative voltages from the line to MPMS
such as Site Manager, MXP2 188 and Mirador.
3.2 Analog Channel Setup
The MPMS' analog channel needs the proper scaling factor according to the AC voltage
range (see following table). Please refer to the user manual of your MPMS for a
complete description of steps to follow in order to configure your MPMS accordingly.

4. INSTALLATION
4.1 Tools and Equipment
The following tools and test equipment are recommended:
•Safety glasses
•Crimping tools (Amp model: 90123-2), pliers and soldering iron may also be used.
•Tie-wraps or friction tape
•Tarpoline, canvas
•RMS multimeter with clamp-on meter
•BX cable 14/2#
•Belden cable #9305 or #20 AWG stranded
NOTE: unpack and verify with the “Material list” that all the material is received and
in good condition.
4.2 Mounting the System
The SDTA-01 is installed in an electrical room and as close as possible to the
measurement AC voltage in order to minimise risk associated with the transmission of
AC voltage. Install the SDTA-01 on any flat wall surface. Do not install the SDTA-01
in electrical box.
NOTE: protect the equipment from liquids.

4.3 Cables and Connections
This section provides the general installation procedures and demonstrates how to
interconnect and put into service an SDTA-01.
NOTE: you can find connectors J1 to J8 by locating their names on the board inside
the casing.

SDTA-01 4BINSTALLATION
4.3.1 General Information
•In order to install the equipment properly, it is important to have a global view of
the installation and to read the following instructions before starting.
•For more details on the operation of MPMS equipment, please refer to their own
user manuals.
4.3.2 Connecting the Primary to 110 VAC
Refer to Table 2 and Figure 3 for more detail.
1. Remove the two screws holding the SDTA’s cover in place, using a screwdriver.
2. With a BX 14-2 cable, wire a 20A AC breaker maximum, coming from the
electrical box to supply the SDTA-01.

Refer to Table 3 and Figure 4 for more detail.
1. Remove the two screws holding the SDTA’s cover in place, using a screwdriver.
2. With a BX 14-2 cable, wire two 20A AC (maximum) breakers, coming from the
electrical box to supply the SDTA-01.

4.3.4 Connecting the Secondary Circuit
Refer to Table 4 for more information on cabling the secondary circuit.
1. Link the secondary to a MULTITEL Power Monitoring System using two
24-gauge stranded wires.

RED OUTPUT 1 AN+
BLACK OUTPUT 2 AN-
2. Put the cover back on the SDTA-01 and its screws.
* JX is the corresponding connector on the MPMS.
NOTE: use the cable conduit #3110 to keep the output cable away from the primary
circuit. Pin 1 of J8 is linked to the positive analog channel of the MULTITEL power
monitoring system and pin 2 of J8 is linked to the negative analog channel. Crimp for
a MXP2 188 installation or screw directly into the Weidmuller connector for a
Mirador or Site Manager installation.
4.3.5 Definition of Connectors
The following section contains a description of connectors J3 and J8.

SDTA-01 5BMAINTENANCE
5. MAINTENANCE
5.1 Calibration
The SDTA-01 does not need a periodic maintenance, however if the output values
provided by the SDTA-01 are erratic (after verification), the MULTITEL power
monitoring system’s may be programmed to compensate the differential in
measurement.
Tools and/or equipment required for calibration:
•AC voltage clamp-on RMS multimeter
•Terminal or portable computer to communicate with MULTITEL power
monitoring system (Emulation of VT-100, ANSI in some case)
5.1.1 Mirador or Site Manager
1. Check that the analog channel scale is adjusted correctly.
2. Disconnect the wire from the connector associated with the analog channel.
3. Short-circuit the 2 wires of the analog channel.
4. Enter the CALIBRATION command.
5. Choose 1 for “Analog Channels”
6. Choose the card number and the desired analog channel.
7. Automatically adjust the zero by typing “z”.
8. You can manually adjust the zero with the “+” and “-” keys.
9. Replace the connector wires in place and measure the voltage applied with the
help of a multimeter.
10. Redo the CALIBRATION command, this time specify the value applied (the
value read by the multimeter).
11. Automatically adjust the gain by typing “G”.
12. You can manually adjust the gain with the “<“ and “>“ keys.
5.1.2 MXP2 188
1. Disconnect the corresponding connector for the selected analog channel on the
back panel.
2. Short the 2 pins of the corresponding analog channel.
15

SDTA-01 5BMAINTENANCE
3. Use the CALIBRATION1 command to adjust the zero reading and follow the
instructions.
4. Replace the connector on the back panel.
5. Connect a voltmeter across the same analog signal.
6. Use the CALIBRATION1 command to adjust the scale factor of the selected
analog channel.
7. In response to “ENTER THE APPLIED VALUE:” on the MXP2 188, enter the
voltmeter reading and follow the instructions.
NOTE: for the universal module, it is not necessary to short the input in order to
adjust to zero since the module does that automatically.
5.2 Troubleshooting
This section lists some helpful hints on how to analyze problems that may occur,
because all troubles are unpredictable. When the problem is still not identified after
reading this section, please refer to the Customer service centre.
NOTE: before sending back any defective unit, please make arrangements with your
nearest MULTITEL Customer service centre.

SYMPTOM POSSIBLE CAUSE
No reading, the monitoring
system indicates 0 volts on
the displays
The monitoring system analog channel is disabled (see user
manual of corresponding MPMS.
The analog channel of MPMS is not the right type. MIRADOR-
MXP2 must be SDTA and channel must be true RMS.
There is no AC voltage present at the SDTA-01 inputs.
Verify JP1, JP2 and JP3 setting for the same MPMS you are
installing (optional).
The wiring is not according to specification in the SDTA-01
connector's definition.
The SDTA-01 may be defective if all of the above possible
causes are not true (refer to MULTITEL Customer service).
The reading is erratic
The calibration is not adequate, refer to section 5.1 in this
manual.
The scaling is not adequate, refer to section 3.2 .
The ANALOG channel of MPMS is not configured as true
RMS (refer to MPMS manual).
