Monitoring relay PRI-51 is designated to monitor current levels in 1-phase AC circuits.
Its slight setting of actuating current predeterminate this relay for many applications.
Output relay is in normal state opened. After crossing over the set current level, relay
will closed after set delay time (0.5 - 10 s). When returning from a faulty state to normal,
hystersis (5 %) applies. An advantage of this relay is an universal supplying. It is possible
to monitor load, which doesn´t have the same supply as the monitoring relay PRI-51. It is
possible to increase the range of PRI-51 by using an external current transformer.
Warning
The device is constructed to be connected into 1-phase main and must be installed in
accordance with regulations and norms applicable in a particular country. Installation,
connection and setting can be done only by a person with an adequate electro-technical
qualifi cation which has read and understood this instruction manual and product
functions. The device contains protections against over-voltage peaks and disturbing
elements in the supply main. Too ensure correct function of these protection elements
it is necessary to front-end other protective elements of higher degree (A, B, C) and
screening of disturbances of switched devices (contactors, motors, inductive load etc.)
as it is stated in a standard. Before you start with installation, make sure that the device
is not energized and that the main switch is OFF. Do not install the device to the sources
ofexcessive electromagnetic disturbances. By correct installation, ensure good air
circulation so the maximal allowed operational temperature is not exceeded in case of
permanent operation and higher ambient temperature. While installing the device use
screwdriver width approx. 2 mm. Keep in mind that this device is fully electronic while
installing. Correct function of the device is also depended on transportation, storing and
handling. In case you notice any signs of damage, deformation, malfunction or missing
piece, do not install this device and claim it at the seller. After operational life treat the
product as electronic waste.
