IPC1 USER MANUAL ISSUE 9
-11-
Pilot Latch: Determines whether earth
continuity trips are self resetting or
not
B-emf TIME:
Adjustable time delay to inhibit
main contactor fail following
opening of main contactor
Fan i Level:
Sets the fan current threshold at
which other outlets are allowed to
run
Remote Start:
When “Yes” is selected the IPC
Relay ignores the local start input.
When “No” is selected the local
start/stop inputs control the relay
Ins . TstT:
Sets the trip threshold or disables
the function
7.2 Changing Settings
The procedure for adjusting the settings is
independent of where the values are stored. The pilot
mode should be checked prior to making any other
adjustments to be certain the changes are made to the
desired memory.
1.
Ensure the outlet is stopped.
2.
For Group 2 Settings in RTU Mode, ensure RTU
is on line.
3.
Display the parameter that has to be changed on
the Remote Display Module’s liquid crystal
display.
4.
Momentarily operate the lock push button. A
warning message appears.
5. Press the enter button to acknowledge the
warning message and to confirm that a change is
desired.
6.
Use the left and right arrows to step through the
allowable values until the desired new setting is
displayed. If the right arrow key is pressed when
viewing the last parameter the display wraps
back around to show the first parameter.
7.
Press the enter button to indicate that the value is
the required setting.
8.
Momentarily operate the lock push button. The
display will show a confirming message, then
return to the viewing level.
If the up or down keys are operated during the
procedure the IPC Relay aborts the modifying
sequence.
When changes have been made to the stored values,
the old value and the new value are stored in the
event log.
A separate log immediately proceeds this recording
the time and date that the change was made.
Note 1
While in the diode mode the IPC Relay can be
preset with operating values in the Group 2
memory prior to switching to the RTU mode.
When in this mode the relay uses the Remote
Termination
Unit settings. If the Remote
Termination Unit is replaced with a diode and the
“Pilot Mode” switched back to diode, the settings
will revert back to the values preset in the IPC
Relay.
Note 2
When the relay has been selected for RTU
Mode the RTU must be on line before the RTU
set up mode can be entered.
8. System Control
8.1 Digital Inputs
The IPC Relay has five digital inputs, which are all
voltage free contact inputs. Shorting the two input
terminals together activates them. The inputs are
MCI, start, stop, lock and reset.
The status of inputs can be displayed on the Remote
Display Module (Level 6, Positions 2 and 3).
8.2 Output Relays
The IPC Relay has output relays to control the main
contactor (MCR) and the circuit breaker (CBR). Both
relays are fail safe with respect to power supply loss
and are controlled on the basis of protection
functions.
Relay 3 has a selective function. (See section 6.1).
RL4 applies 110V for the Insulation Test. (See
section 3.2.2).
The status of the relays can be displayed on the
Remote Display Module (Level 6, Position 1).
8.3 Open Collector Outputs
The IPC Relay has eight open collector outputs,
which are driven through opto couplers to provide
additional indication if required. These can be used
to drive LED’s, or additional relays (with appropriate
drive circuitry). The eight outputs correspond to the
LED’s on the display module, turning on whenever
the corresponding LED is flashing. The signals are
available on the IPC Relay’s base pins 35-42, and the
common is on pin 34.
