its sequence from 2 fast and 2 delayed operations to 2
operations on FTD TCC when Fast Trips Disabled is enabled.
High current trip
The High Current Trip (HCT) feature will trip at a selected
multiple of minimum trip for phase and ground. The HCT
definite time is programmed independently from the normal
TCCs. This feature is independently selectable for each
protection profile.
High current lockout
The High Current Lockout feature will automatically lockout
the control on the selected operation when current
exceeds a programmable level. The active trip information
for the lockout and current threshold for each operation
are selectable for phase and ground. This feature is
independently selectable for each protection profile.
Sensitive ground/earth fault operation
The control has a Sensitive Ground/Earth Fault Trip feature
that provides tripping of the recloser after a programmable,
definite time for ground currents below normal ground
minimum trip levels. The feature has programmable
operations to lockout and reclose intervals independent of
the ground settings. This feature is independently selectable
for each protection profile.
Thermostatically controlled heater
The control has a standard thermostatically controlled
heater for humidity control. The heater is powered from
input voltage.
Metering
The control provides instantaneous and/or demand
metering with programmable integration intervals for the
followingfunctions:
Real, reactive, and apparent power for each phase and total,
including power direction, on an individual phase basis.
Demand currents and power on a per phase basis.
Instantaneous currents, including ground current.
Instantaneous voltage on a per phase basis.
Instantaneous frequency.
Positive, negative, and zero sequence voltages.
Instantaneous power factor on a per phase basis.
Sync phase angle difference.
Sequence of events recorder
The Form 4D control contains capabilities to perform
Sequence of Events with time-stamping.
Factory-defined event types include:
Phase Trip and Lockout.
Local Trip/Lockout (Front Op. Panel).
Frequency Trip.
Ext. Close Request.
Phase Fault.
Overcurrent Reset.
ote:N The user can select additional event types from
alarm configuration.
The Event Recorder maintains a minimum of 1000 events.
The most recent 50 events (event name and timestamp)
are viewable on the front panel LCD display. Refer to
S280-104-2 Form 4D Control Programming Guide for
additional information.
Recloser duty monitor
The Form 4D recloser control software is equipped with
a Recloser Interrupting Duty Monitor. The Duty Monitor
accumulates the summation of Current
1. 5
for all interrupted
currents on each phase. This feature permits programmable
entries to preset the duty of an existing recloser. The
recloser duty monitor displays interrupting duty in percent
of duty used. If the duty cycle monitor exceeds 100%, the
recloser should be examined for maintenance.
Contact I/O module option
The base control has no I/O modules as part of the
standard configuration. The add-on I/O module provides four
configurable output status contacts and four configurable
input control contacts. Each status contact is configurable
using ProView NXG software to combine status functionality
along with Boolean algebra. Default output status contacts
for the first I/O card are: Lockout, Recloser Open, Recloser
Closed, and Control OK. (Refer to Tables 4 and 5 for the
whetting voltage range accepted by the contacts.) Default
input control contacts for the first I/O card are: Ground Trip
Block, Non-Reclose, Close, and Trip & Lockout.
Up to four I/O modules are available as options to
provide up to 16 output status contacts and 16 input
controlcontacts.
ote:N For every one terminal block accessory ordered, the
maximum additional I/O allowed quantity is reduced
by one.
The expansion I/O modules are completely user-configurable.
TCC Editor II
Coordination and actual time current modifications are
available with a graphic interactive TCC Editor or similar
graphical software.
The TCC Editor II includes a complete database of industry-
standard recloser time current curves (TCC), including ANSI
and IEC types, along with the ability to customize TCCs with
multipliers, constant time adders, or minimum response
time adders. Also, the user is able to create custom time
current curves through data point entry. Each modified TCC
can be identified with a user-customized name. The grid and
format for presenting the TCCs has a user-adjustable scale,
including the option of presenting multiple TCCs in various
user-configured colors.
