DSR DELAY ON STAR/DELTA
Read all instructions carefully
The multifunction time relay
DSR
is a device standardised in 1-module DIN container,
designed to operate in environments with normal pollution level.
It is designated to manage the three-phase motors start-up and permits, after a certain delay,
the passing from star to the delta confi guration.
SAFETY WARNINGS
During the installation and operation of the instrument, proceed in accordance with the
instructions below:
1) The instrument should be installed by a competent operator following the
installation diagrams carefully
2) The instrument should be installed in a panel from which no access can be gained to
the terminals after installation
3) Do not power or connect the instrument if any part of it is damaged
4) The electrical system of the building in which the instruments is to be installed
should have a switch and a protective device against over-currents
5) The instrument is designed for installations with over-voltage category III and
pollution level 2, in accordance with the EN 61010-1 standard.

OPERATION
•
Operation conditions
While installing this device it is necessary to consider temperature rate of ambient devices
so the operation temperature stated in technical parameters is kept. It is necessary to
ensure air circulation so the operation temperature is not exceeded in any case.
It is necessary to avoid placing devices close to sources of electromagnetic disturbances to
ensure their correct function.
It is necessary to pay attention while connecting products to the circuit with appliances
that create electromagnetic disturbances (conductors, motors), or power cables close
to them. It is recommended to have the connection cables of a product (supply and
operating inputs) as short as possible and have them led separately into power conductors.
•
Handling and use
Use a screwdriver with an approximate width 2mm for installation and setting
Do not use brute force to screw input terminals (maximally 0,5 N/m).
Do not put exceeded pressure on to the holding parts of terminals so the inner
construction of the device is not damaged.
Protect the device against falls and excessive vibrations
Do not overload relay output contacts, mainly while using loads of another category
then AC1
If contacts of relay melted while switching big loads, it is necessary to use an inserted
contactor or power relay rated for required load in the current installation.
For a correct setting of the relay, observe the following operations:
– setting the Rought time setting
“t1”
with its potentiometer (see time ranges in the box
“OPERATING DIAGRAMS”)
– setting the Fine time setting with its potentiometer (between 10% and 100% of the
Rought time setting)
– setting the delay time
“t2”
for the commutation from star to delta confi guration
(between 0,1 second and 1 second).
