REFERENCE
The voltage adjustment of the GRTD-TH3 controllers can be done via trimpot (Vad) or via analog
input or digital input as shown in the diagram in figure bellow. The regulator will control the measured
voltage using as a reference the sum of the 3 settings.
When the three references are simultaneously being used there may be a voltage up to ± 30%
above the reference voltage.
VOLTAGE ADJUSTMENT VIA VAD POTENTIOMETER
The internal potentiometer setting adjusts the reference between 160 to 300Vac when the
equipment is operating at the lowest sensing voltage range through terminal E1, when the
equipment is using sensing voltage in the longest operating range through terminal E2 this variation
will occur from 330 to 600Vac. The clockwise increases the voltage reference and counterclockwise
decreases the reference.
VOLTAGE ADJUSTMENT VIA ANALOG INPUT
➢
Variation of +15% à -15% on the reference voltage.
➢
-10 Vcc à +10 Vcc
➢
Consumption of up to 10mA at the analog inputs.
VOLTAGE ADJUSTMENT VIA DIGITAL INPUT
The setting via Digital Input is made by dry contact between the CM terminal of the voltage regulator
with the UP terminal or the DW terminal of the voltage regulator.
The contact made at the CM terminal with the UP terminal of the voltage regulator increases the
output voltage of the ramp generator by tripping from the Un (generator output voltage) to 15%
above Un at a preset time of 10 seconds.
The contact made at the CM terminal with the DW terminal of the voltage regulator decreases the
output voltage of the ramp generator by tripping from the Un (generator output voltage) to -15%
below Un at a preset time of 10 seconds.
