KAEL DV-72-RR Quick Start Manual

DV – 72 - RR
REGULATOR CONTROLLER
General Informations:
Used for servo motors to keep the output voltage at the desired set value.
- The device measures both the input voltage and the output voltage and keeps the output voltage
constant by controlling the servo motor control output.
- Calculates measurements using the True RMS method.
- Interferes with the motor speed.
- Stores in memory the lowest and highest over voltage values of the input voltage.
This can be followed by the manufacturer's operating conditions.
BUTTONS :
By pressing the up key you can reach the measurement screen with
the input overvoltage value,
By pressing the down key you can see the Input undervoltage value.
INTRODUCTION TO PARAMETERS:
Press the set button for 5 seconds.
Set: In this menu, you can access following parameters with key button: Set, h-1, h-2, Spd, Pou, Clr, uSt,
Alt, hYS, dLY-oFF, dLY-on and qut. When Set menu is accessed all parameters flash on the screen. To change
parameter value, first press the set key, then change the value with the direction keys. Press set key to store the desired value.
qut : Press Set to return to the measurement screen.
USING THE KEYS:
The Set menu is entered with the set key. The parameters in the menu can be accessed with the arrow keys. Enter the parameters with the Set key
and change the value with the arrow keys. With the Set key, the parameter which value has been changed is memorized.

Control according to input voltage:
■ % Input Overvoltage SET value max. limit should be selected lower than the
open-circuit voltage value.
Sample :
If the switch limit is set as 250 volts, the% input Overvoltage SET value
should be ≤ 249 V.
■ % Output Low voltage SET value min. limit should be selected higher than
open-circuit voltage value
Sample :
If the switch limit is set as 170 volts, the% undervoltage SET value
should be ≥ 171 volts. Otherwise, it gives Engine error (dEr). In this case,
the output opens the relay contact. When the voltage returns to the normal
values, (dEr) the engine failure occurs and the device brings the output
voltage of the regulator to the set value. The output relay turns the contact off.

■ Output voltage due to overload, due to voltage pulse,
% output Overvoltage SET value or % output Low voltage SET value,
If the dLY exceeds the oFF time, the device opens the relay contact. When
the output voltage returns to% hYS and dLY is actie, the device turns off the
relay contact.
■ It is advisable to select the set values as follows.
