DESCRIPTION

● Three-phase delta-star motor control,

● current decrease during high power

motor start,

● device mode optical signalling (LED

red),

● supply voltage optical signalling (LED

green),

● trigger by applying supply voltage,

● starting time adjustment (STAR sys-

tem),

● interval time adjustment of STAR to
DELTA switching,

● two independent relay outputs, dry

contact 2 x NO/NC of 10 A capacity,

● mounting in distribution boards (TH35

rail).

The PCM-08 time relay is used to

control the STAR-DELTA contactor
switch. It is applied in three-phase mo­tor control systems. This control me­thod allows to reduce starting currents
in case of motor units with a capacity
of more than 4-5 kW and additionally it
provides safety. The PCM-08 device has
two independent relay outputs activated
according to the settings of P1-P3 po­tentiometers. It is possible to adjust the
starting time (in the STAR system) and
time interval of star to delta switching.

Relay operation is triggered by applying

power supply voltage to the L, N supply
terminals. The device is designed to be
mounted in distribution boards (TH35
rail). The LEDs on the front panel in­dicate power supply (LED green), and
device operating mode (LED red).

FUNCTIONIG

The PCM-08 device is equipped with two electromagnetic relays at its end, which control
the correct contactors that switch the motor winding according to the adjusted time of start
and interval (P - „star” contactor, P - „delta” contactor).

After power supply is switched on, the PK1 relay switches on the contactor responsible
for switching the motor windings into STAR system for the adjusted time. After that time
has elapsed, the relay switches off PK1 relay and the interval time, adjusted by P1 poten­tiometer, is measured. After the interval time has elapsed, the PK2 relay switches on. It is
responsible for switching the motor windings into DELTA system. PK2 relay remains on until
there is no power supply in L, N terminals.

Switching on PK1 relay – normally closed 11-14.

Switching on PK2 relay – normally closed 21-24.

Measuring delta start time is indicated by a ashing red LED with a frequency of 1 second.
Whereas delta operation is optically signalled by a continuous LED light.

MOUNTING

1. Disconnect power supply by the phase

fuse, the circuit-breaker or the switch-

-disconnector combined to the proper

circuit.

2. Check if there is no voltage on con-

nection cables by means of a special
measure equipment.

3. Mount the PCM-08 device on the

TH35 rail.

4. Connect the cables with the terminals

in accordance with the installing dia-

gram.

5. By means of P1 ÷ P3 potentiometers

adjust:
a) starting time in the star system

t – potentiometer P2 (1 ÷ 100 s)

b) starting time multiplier – P3 poten-

tiometer (1 ÷ 10 with strobe ‘1’)

t

STARTING

= t x multiplier

(potentiometer P2) (potentiometer P3)

c) star to delta switching time (P1 po-

tentiometer)

6. Switch on the power supply from the

mains. After power supply voltage is
applied to the L, N supply terminals,
the P

and P output relays switch ac-

cording to the adjusted time.

The device is designed for single-pha-

se installation and must be installed in

accordance with standards valid in a

particular country. Installation, connec-

tion an d contro l should be ca rried out by
a qualied electrician staff, who act in
accordance with the instruction manual
and the device functions. In case of ca­sing dismantling, the guarantee is lost
and an ele ctric shock may occ ur. Before
installation make sure the connection
cables are not under voltage. The cru­ciform head screwdriver 3,5 mm should
