FRC FDA700 for Delta Winding
The FRC FDA700 for Delta Winding is a three-phase generator output display panel rated for 50/60 Hz generators from 10 to 135 kW. It displays generator frequency, voltage, and current, and has a built-in hourmeter. The display module is waterproof and can be mounted anywhere on the electrical panel, while the signal interface module is mounted close to the current sensors and voltage transformers for short cable runs.
The FDA700 has several safety features, including voltage fluctuation, current overload, and high-temperature warnings. It also has an optional audible alarm buzzer and temperature sensor.

INTRODUCTION
Overview
The three phase generator output display panel is rated for 50/60 Hz generators from 10 to 135 kW with delta or star windings.
The display module has ultra-brite LEDs that show the generator frequency, voltage, and current. When the generator is off line the display shows total accumulated generator hours.
The signal interface module is mounted close to the current sensors and voltage transformers so that cable runs are short. Current and voltage information is passed to the display module over a two wire datalink.
Built in safety features include voltage fluctuation, current overload and high temperature warnings.

GENERAL DESCRIPTION
Components
The three phase generator display consist of the following components:
Display Module
Signal Interface Module
Three (3) Current Sensors
Three (3) Voltage Transformers
Temperature Sensor (Optional)
Audible Alarm Buzzer (Optional)
Cables
Display Module
The display module is waterproof and can be mounted anywhere on the electrical panel. The display module has a square flange with overall dimensions of 4 1/4" by 4 1/4".
A cutout hole of 3 3/4" in diameter is required.
Signal Interface Module
The signal interface module is waterproof with overall dimensions of 5 7/8" by
3 3/4" by 1 7/8". Clearance for the cables is required. This module is mounted close to the current sensors and voltage transformers so the cable runs are short. Current and voltage information is passed to the display module over a two wire datalink.
Current Sensor
The current sensors are used to measure current flow through a wire by electromagnetic induction. Each phase wire to the main circuit breaker is run through a current sensor opening (hole); one wire through each current sensor.
Voltage Transformer
The voltage transformers supplied work with 120 or 240 volt AC systems.
The transformers should be securely mounted inside the electrical box.
Temperature Sensor (Optional)
The optional temperature sensor is installed as required.
Audible Alarm Buzzer (Optional)
The optional buzzer is installed as required.
Cables
Refer to the Wiring Section.

INSTALLATION
Ensure that the generator power rating and the display rating match. Refer to
Programming Section.
Install Display Module
1. Measure and mark mounting location for display module panel cutout and mounting screw holes. Make sure there is clearance behind the panel for the module and cables before cutting holes. Refer to Figure 2 for layout and dimensions.
2. Cut out a 3 3/4" mounting hole in panel.
3. Drill four holes, clearance or tapped, for #10 mounting screws.
4. Place display module in position and secure with screws.
5. Connect cable at rear of the display module. (Refer to Wiring Section.)
Install Signal Interface Module
This module is mounted close to the current sensors and voltage transformers so the cable runs are short. Current and voltage information is passed to the display module over a two wire datalink.
1. Measure and mark mounting location for control box mounting screw holes.
Make sure there is clearance for the box and cables before drilling. Refer to
Figure 3 for layout and dimensions.
2. Drill four holes, clearance or tapped, for #8 mounting screws.
4. Place box in position and secure with screws.
5. Connect cables at top of the box. (Refer to Wiring Section.)

Install Current Sensor
Three current sensors are supplied. It is best to mount the sensors in the circuit breaker box. For each phase that is to be monitored, run the wire from the generator through the current sensor opening (hole) to the input side of the circuit breaker.
(Refer to Wiring Section.)
Install Voltage Transformer
The voltage transformers supplied will work for 120 or 240 volt AC systems. The transformers should be securely mounted inside the electrical box.
Each transformer will be connect to show line voltage phase and neutral or phase to phase for star or delta windings of the generator. (Refer to Wiring Section.)
Install Optional Temperature Sensor
The temperature sensor is installed as required. (Refer to Wiring Section.)
Install Optional Buzzer
Install the buzzer close to the control module so the audible warning is easily associated with the visual warning on the display. The optional buzzer provided by
FRC requires a cutout hole of 1-1/8" (1.125"). (Refer to Wiring Section.)

OPERATION
On power-up the display shows the kW rating and the winding type (delta or star) for three seconds.
MODE Button
During normal operations the mode button is used to display the accumulated hours and hydraulic oil temperature if this option is installed.
The first time the MODE button is pressed, the display shows generator hours.
Generator Operating Time is:
50 hours
Pressing the MODE button again switches the display to show sensor temperature.
Hydraulic Oil Temperature is:
150 °
Pressing the MODE button again returns the display to normal operations.
Over Current Warning
When the generator is operating outside the range of its rated capacity, the current display flashes. An optional audible buzzer can also be connected for audio warning.
Voltage Out-Of-Range Warning
If the output voltage (120/240 VAC) is below 80/200 VAC or above 140/270 VAC, the voltage display flashes. This gives the operator an indication that the generator output falls outside the safe operating level. There is no audible alarm for the voltage out of range warning.
Temperature Sensor(Optional )
This warning is activated if the temperature sensor rises above 180 °F. The frequency readout flashes OIL to warn the operator and the audio alarm is activated.

LINE Displays and Button
On power up the LINE displays are set to auto.
In auto the displays scroll continuously through all selectable options and show the corresponding voltages and currents in the display windows.
To read the voltage and current for a specific line press and hold the LINE button until the number corresponding to the desired selection shows in the LINE window.
(Refer to the chart next to the LINE window.)
Note: When line selections 4, 5, and 6 are active the AMPS window shows
3 dashes.
Leave the display in auto during normal operations to monitor all voltage and current levels.
