SATEC C192PF8-RPR - Manual (Page 7)

2 Chapter 1 Introduction
• Manual, self-adapting automatic and optimizing automatic operation
• Full four-quadrant operation
• Selectable target power factor or reactive power setpoints
• Two PFC setpoint ranges for day and night operations selectable via a
status input
• Target power factor range from 0.5 (inductive) to -0.5 (capacitive)
• True and displacement power factor setups
• True and fundamental’s reactive power setups
• Extensive capacitor banks protection via programmable alarm setpoints
(no-volt, over-voltage and high harmonics override conditions)
Display
The front panel features bright LED displays (three windows, up to 43 pages) with
adjustable display update time. Display auto scroll is available on the main screen
with a programmable scroll interval of 2 to 15 seconds. Automatic return to the
main screen is available after 30 seconds of uninterrupted use. The front panel
also includes:
• Relay status bar showing output status of the 8 relays
• Alarm/Manual Mode LED providing a local indication when a predefined
alarm condition appears (the LED is lit constantly) or when the PFC
operates in Manual Mode (the LED flashes). The alarm LED is shut off
manually (by pressing on both up and down keys for more than 5 sec)
• RXD/TXD LEDs showing communications receive/transmit status
Setup is menu driven, with optional password protection. 16 programmable
setups are provided for alarm and control functions (for programmable
parameters, see ‘Measured Parameters’ below).
Communications are available using an RS-232 or RS-485 standard (factory
set), with Modbus protocol. 120 user assignable registers are available in Modbus
protocols.
Eight relays are provided for capacitor banks switching, energy pulsing (KYZ) or
alarm and remote control. Contacts of six relays may switch loads up to 250V, 5A
AC and are recommended for alarm and remote control; contacts of two relays
may switch loads up to 250V, 3A AC and may be used for energy pulsing.
One optically isolated analog output is provided for remote monitoring or
control. Current loop options are 0-20 and 4-20 mA. The analog output must be
used with an external power supply.
Four common-use event/time counters are provided for counting user-defined
events or their duration. These can be used for counting total operation time of
generators or overload time of transformers or power lines. The counters are
operated and released by user-defined triggers.
Eight dedicated relay operation (switching cycle) counters are provided for
counting the number of PFC relay operations (number of complete switching
cycles).
