HATHOR-16TM SERVICE MANUAL
3 GENERAL DESCRIPTION
The mains power supply 240V 50Hz should be connected to «(1-1) – (2-2)»
terminals of the HATHOR-16TM. For wiring convenience terminals 1-1 are
the one connection point and 2-2 terminals - another connection point.
Output contacts have changeover relay 3 – 4. In a time of exploitation of
relay a strap is set 5-6.This strap is connect the internal accumulator of
reserve clock motion. For warehousing of device it is recommended to take
off this strap that will substantially increase lifetime of accumulator. Power
load is being connected using terminals 3-4.
If the HATHOR-16TM detects the unallowable OVER/UNDER voltage, then it
will turn OFF the power load by opening the contacts 3-4 and in case of
using the contactor that will turn OFF the power for the magnetic coil of the
contactor and thus disconnect any required equipment. As soon as voltage
parameters restore and return back to normal values – HATHOR-16TM will
automatically turn ON the power load within the preset autoreclosing time
delay. Present status of the relay - ON/OFF states of the output contacts are
indicated by green LED light “ON” in the left upper corner of the front panel
(Figure 1; point – 1). Current operation mode of the HATHOR-16TM is
marked by green LEDs “F”, “U”, “H” on the front panel (Figure 1; point – 7).
All the adjustments and parameter settings could be subdivided into two
groups: BASIC and PARAMETER settings.
