TE Connectivity PLL/D-100/120 Installation And Operating Instructions

Synchro-check Monitor PLL/D-100/120, PLL/D-173/240,
PLL/D-380/480, PLL/D-277/500 DIN-rail mounted
Introduction
This unit compares the voltage, frequency and phase angle of two
supplies and operates a relay according to the synchronicity of the
supplies. If the two supplies cease to match, the relay operates to
provide a control output. The relay output can be used for alarm or
control purposes.
The unit also provides a dead bus function. If the bus supply fails, the
relay operates and the output can be used to switch in an emergency
generator. LEDs indicate power on, relay and dead bus status.
Controls on the front panel set the trip points at which the relays and
LEDs operate:

Degree of synchronicity Ux (%Volts)

Nominal voltage (Un)

Dead bus function on/off
The unit is powered from the generator supply.
These instructions contain important safety information. Please read
them thoroughly before commissioning, operating or maintenance of
the unit.

Operation
The green LED lights shows when the power supply is on.
While the two supplies match in voltage, frequency and phase to the
degree set by the %Volts control, the Sync LED lights and the relay is
energised.
If one supply varies such that they no longer match to that degree, the
Sync LED goes off and the relay de-energises.

Installation and Operating
The differential trip levels help to prevent relay chatter as the
monitored voltage level varies.
277/500 As the relays have changeover contacts, the relay outputs can be
inverted by wiring to the alternative terminals 15-16 or 25-26.
277-
500V
If the generator voltage falls below the Uon level, the unit ceases to
600V
operate, the relay de-energises and the Sync LED goes off.
700V
With Dead Bus On, if the bus voltage falls below the Udbon level, the
166V
relay energises and the Dead Bus LED lights. The relay can be used
5 VA /
to turn on an emergency supply in the event of bus supply failure. The
2.8W
relay will de-energise again and the LED will go off when the bus
voltage rises above the Udboff level.
Note; Red LED indicates fault condition, not relay status
Installation
The unit is intended for mounting on a standard DIN rail. Hook the unit
onto the top of the rail and press the bottom of the unit until it locks in
place. To remove the unit from the rail, lever down the black tabs at
the bottom of the unit to release it from the rail.
The unit is intended for use in a reasonably stable ambient
temperature within the range -20 to +55°C. Do not mount the unit
where there is excessive vibration or in excessive direct sunlight.
