When the phase or ground current exceeds its programmedminimum-trip value and associated time-current-curve (TCC)timing, the control initiates the programmed sequenceof recloser tripping and reclosing operations. If the faultis temporary, the control ceases to command recloseroperations after a successful reclose, and the control resetsto the start of its operating sequence after a preset timedelay. If the fault is permanent, the control performs itscomplete programmed sequence of reclose commandsand locks out with the recloser open. Once locked out, thecontrol must be closed via the operator panel or SCADAcommunications. This resets the control to the start of theoperating sequence.The following chain of events occurs for an operatingsequence of two trips to lockout (one trip on TCC1, one tripon TCC2):1. The overcurrent signal is integrated with time on theselected curve for the first trip operation (TCC1) toproduce the signal which energizes the trip circuit.2. Energizing the trip circuit connects the supply to the tripsolenoid to open the recloser.3. Upon opening, the control starts timing on the firstreclosing interval-delay time.4. Upon expiration of this reclosing interval-delay, a closingsignal is issued from the control, closing the recloser,and selecting the time-current characteristics for thesecond trip operation (TCC2).5. If current remains above the minimum-trip level, therecloser will trip on TCC2 and lockout the recloser.Control front panelThe Form 4D control front panel is illustrated in Figure 3.The front panel is separated into two clearly identified,color-coded sections:●● Programming Panel: The top portion of the front panelis used for programming the control and providing LEDstatus indication.●● Operating Panel: The lower portion of the front operatingpanel is used for operating the control and recloser.The control includes a Power Save feature that will turnoff the LEDs and backlit LCD display after 15 minutesof inactivity at the front panel (no buttons pressed). TheCONTROL OK and HOT LINE TAG LEDs are not affected bythe power save mode. Pressing any key on the front panelwill turn the LCD backlight on and restore all LEDs to theircurrent on/off states.The control includes a Reset Menu feature that will causethe LCD display to revert to the root menu after 15 minutesof inactivity.Figure 3.

The LCDdisplay panel contrast is field-adjustable to allow for variousmounting heights and applications. Press the FUNC keyand UP or DOWN arrow simultaneously to increase ordecrease contrast.The keypad functionality is summarized as follows.●● The  (up) key can be used for the following tasks:●● Scroll to the next item up on the current Menu level.●● If already at the first item of the current Menu level,return to the last item of the current Menu.4 operation inStrUCtionS MN280049EN September 2017Form 4D Microprocessor-based pole-mount recloser control installation and operation instructions
