Kyle Form 5/Triple-Single Microprocessor-Based Recloser Control Installation and Operation Instructions
Sensitive Ground/Earth Fault
Operation
Sensitive Ground/Earth Fault (SGF/SEF) is active when
all three phases are closed. For SGF faults, all three
phases trip at one time.

Recloser Interface (RIF) Module

The Recloser Interface (RIF) Module provides the inter-
face between the recloser and the CPU module, as well
as the interface between the voltage sensors and the
CPU module. The RIF module provides three current
transformer inputs, three open and close circuits and
three sets of OPEN, CLOSE, and yellow operating handle
LOCKOUT status inputs (one for each phase). These sig-
nals always indicate the true state of each Form 5/Triple-
Single recloser, regardless of the position of the yellow
operating handle.
One connector on the bottom of the control cabinet pro-
vides the connection for all three phases of the Kyle Type
NOVA-TS recloser.
The RIF board accepts either 12, 120, or 240 Vac voltage
inputs for metering. The factory configuration is outlined
on the module label and can be customized to user spec-
ification. See RECLOSER INTERFACE (RIF) MODULE
CONFIGURATION section of this manual.
Central Processing Unit (CPU)
Module
The CPU module is the center of the Form 5/Triple-Single
control. The CPU contains a 32-bit micro-controller, a Dig-
ital Signal Processor, RAM and EEPROM memory, and a

16-bit analog-to-digital converter. The CPU module
accepts 16 analog inputs which it routes through the digi-
tal signal processor, which samples 32 times per cycle, to
compute harmonic analysis to the 15th harmonic.

Discrete Interface (DIF) Module

The Discrete Interface (DIF) module allows users with
existing RTUs the ability to interface with the Form
5/Triple-Single control. The DIF module contains 12
inputs and 12 outputs for remote or supervisory functions.
Each Form 5/Triple-Single control can accommodate two
DIF modules. See DISCRETE INTERFACE (DIF)
ACCESSORY section of this manual.

Power Supply Module

The Power Supply module is designed to accept 100 to
134 Vac or 200 to 268 Vac user-supplied input power at
either 50 or 60 Hz.
The Power supply module (connection P9) provides
power to the auxiliary communication equipment such as
transceivers and modems. Auxiliary output provides 24
Vdc (12 Vdc is available) for user loads. The auxiliary
power supply has the capability to provide a load of up to
40 W peak (1 second) and 3 W average. The auxiliary
power is fused and current-limited to prevent user loads
from disabling the control.
If ac power is lost, the control batteries power the control
until the battery voltage drops below 20.5 V at which point
the power supply disconnects the battery from the load.
