LD-UAC

Universal AC Controller

The LD-UAC universal AC indicator and

alarm controller is ideal for monitoring

and controlling input power, voltage,

current or frequency in a wide variety of

applications.

This controller has been designed for

ease of use, with intuitive, scrolling text

prompts that guide you step-by-step

through the setup process. The front

panel includes 5 buttons, for simple op-

erator interface, and the large 4-digit

display ensures that the gures can be

easily read from a distance.

D _ _ _ AVE SAMPLES scrolls across the display and toggles with the currently

selected averaging. Using the and buttons, alter the number of input

samples that the controller will average, and then press .

Increasing the number of samples will stabilise measurement, but it will also slow down response rates.

E _ _ _ AVE WINDOW scrolls across the display and toggles with the currently

selected averaging window value. Using the and buttons, alter the signal

averaging window. Then press .

If your input signal contains large noise spikes, you can increase the size of the averaging window to ensure that these are still averaged. However, increasing the window size too far will reduce the ability of the controller to respond quickly to real changes in input signal. Setting

AVE WINDOW to 0 will give continuous averaging as per the selected averaging samples.

F _ _ _ INPUT SETUP scrolls across the display and toggles with SKIP. You are now

back at 5.2A. To edit dierent input type, follow the instructions from 5.2A–F

again. If you do not wish to edit another input type, press now to skip to 5.3.

5.3 - Energy setup

The energy function allows you to see the total amount of energy that has been used in W/hr, kW/hr or MW/hr.

A _ _ _ ENERGY SETUP scrolls across the display and toggles with SKIP. Press

to skip to 5.4, or the button and then to ENTR (enter) energy setup.

B _ _ _ RESOLUTION scrolls across the display and toggles with the currently se-

lected energy resolution. Using the and buttons, select: W, KW or MW,

and then press .

` If the resolution was set successfully, setup will proceed to 5.3C. n _ _ _ SCALING ERROR - CHANGE ENERGY SETTINGS!

If you see this message, then the combination of settings that you have

selected in Power Resolution (5.2B) and Energy Resolution (5.3B) will

produce values which are too large for the controller to process or display.

To correct this, modify the settings in 5.2B or 5.3B.

C _ _ _ CUTOFF scrolls across the display and toggles with the currently selected

power cuto value. When the power input value falls below the cuto value,

the energy register will stop accumulating power, and will pause until the input

power is greater than or equal to the cuto value again.

Use the

and buttons to adjust this value as required, and then press .

D _ _ _ ROLL OVER scrolls across the display and toggles with the current setting.

If rollover is ON, then when the energy value exceeds 9,999, the display will roll

to 0 and continue accumulating. If rollover is OFF, then the display will read

OVER in this situation. Use the

and buttons to turn the rollover feature

OFF or ON, and then press .

Note that the ROLL OVER feature does not produce any output pulse or other indication when it rolls over. (An output pulse can be activated on a setpoint with its data source set to Energy. See 6.2F for more information, and to enable this feature.)

If calibration fails, _ _ _ CALIBRATION FAILED will scroll across the display and

you will be directed back to the operational display. The most likely cause of this

error is that the controller could not detect any change in input signal during

calibration. Check your signal and connections, and repeat the procedure.
