Description

Application
The SQX 96 without display is a microprocessor-controlled synchronoscope. It is supplied purely as a display and is used for manual or semi-automatic synchronizations. The integrated enable relay is activated as soon as the set synchronizing conditions are met. The connection is made via a terminal strip on the back of the device.
The SQX 96 with display is also equipped with an LC display. The LC display is used to show the mains voltage and the generator voltage and their frequencies. This allows two separate voltmeters and two frequency meters to be replaced.

Function / Design
The instrument has 24 LEDs arranged in a circle, which are used to display the instantaneous phase difference with a resolution of 20°. In the synchronization range between -20° and +20° the resolution is increased (5° el. degrees).
The green SYNC. LED lights up when synchronization conditions are met. A red ΔU LED lights up when the voltage difference exceeds the set value.
On the back of the instrument there are three potentiometers for setting the synchronization conditions:
• for setting the permissible phase difference Δφ
• for setting the permissible voltage difference ΔU
• for setting the switch-on delay of the relay (DELAY)
The enabling relay is activated (permanent contact) when the phase difference and the voltage difference are within the set ranges for the duration of the set delay time. The permanent contact opens again if only one value is outside this range. Activation of the relay is indicated by the instrument‘s SYNC LED.
