7. Carefully transport the control to a suitable
servicefacility.

Preliminary testing with no AC available
If the Form 4D control is not in service and requires
energization for preliminary testing, it can be powered up
with battery power only.
1. Open the swing panel and locate the push-button switch
recessed inside the control side panel (Figure 36).
Figure 36. Location of push-button switch on the Form
4D control side-panel for power-up with battery power
only. (Inset: DIN rail terminal block tool)
2. Momentarily (4-5 seconds) press the switch with a
non-conductive tool such as the DIN rail terminal block
tool included with the control (Figure 36 inset). The
control will power up.
3. To power down the Form 4D control, unplug the battery
(disconnect the black/red battery connector).
4. Perform a battery charging cycle. Refer to Battery
Charging in the Battery Test and Charging
Procedures section of these instructions.
IMPORTANT
While the Form 4D control is powered in this manner,
the control battery is being continuously discharged.
When the battery voltage drops below 21V DC for 60
seconds, the control will automatically power down.
If the battery is left in a discharged condition, the
battery(s) will sustain permanent irreversible damage.
Therefore, a battery charging cycle should always be
performed after this procedure to bring the battery(s)
back up to full charge.
Testing with type MET tester
The Type MET electronic recloser control tester (Figure 37)
is used for testing the following functions of the Form 4D
recloser control:
Overcurrent Timing.
Reclose Time.
Operating Sequence.
Reset Time.
Minimum Trip Current.
High Current Trip and Lockout.
The MET Tester is completely self-contained, capable of
performing all required checks and tests from a simple
verification of operation to a complete verification of all
operating parameters.
Refer to Service Information S280-76-1 Type MET Electronic
Recloser Control Tester Operating Instructions for proper
setup and use of the MET Tester.

ote:N Setting the S2 switch of the MET Tester to the
“CALIBRATE” position for more than three seconds
[with the MET Tester in the OPEN state] will
cause the Interrupter Malfunction diagnostic to
become active. The control CLOSED and LOCKOUT
LEDs will alternately blink with the OPEN LED. If
the Interrupter Malfunction alarm is configured,
the ALARM LED will also blink. The Interrupter
Malfunction diagnostic state is kept in non-volatile
memory, so it is not cleared when the control
is rebooted. In order to reset the Interrupter
