13. General Repairs
The DLC contains no user-serviceable components within its main enclosure. In the un-likely event that
your DLC needs to be repaired, PULSAFEEDER has implemented a replacement program. Fill out the
Diagnostic form included in the back of this manual, then contact PULSAFEEDER Customer Service at
(585) 292-8000 to enter a replacement order
Within 24-hours a DLC will be shipped to you in a returnable container. Remove the replacement DLC
from the packaging and swap it with the DLC needing repair. Return the DLC in the same packaging
within
30 days . Make sure that there are no components missing from the returned unit – you will be
charged accordingly. Upon receipt of the unit at PULSAFEEDER, an evaluation will be made within 14
days . The unit returned will be refurbished for use in the replacement program.
The DLC has been designed to allow you to replace a defective unit without disturbing the wiring and
conduit The replacement unit will be shipped with the conduit adapter and attached field wiring board
(refer to Figure 2). It is left to your discretion as to whether or not these components are used for the
replacement. (Typically, these are left attached to the wire/conduit and form a 'plug' for the replacement
unit.) When the original unit is returned to PULSAFEEDER, the unused conduit adapter (“new or
“original”) must be attached to the original unit.
13.1 Emergency Manual Pulsar Operation
If your DLC is not functioning, you can operate your PULSAR manually without removing the DLC.
Follow this procedure:
1. Disconnect the power to the DLC at the main.
2. Remove wires to J1 LINE POWER and J3 PUMP MOTOR. Use wire nuts or other code approved
connectors to attach the LINE HOT to the MOTOR HOT, the LINE EARTH to the MOTOR EARTH,
and the LINE NEUTRAL to the MOTOR NEUTRAL.
3. Re-connect the DLC power at the main.
T HE PULSAR MOTOR WILL START IMMEDIATELY ! T AKE ALL NECESSARY S AFETY
PRECAUTIONS .
4. Rotate the manual adjustment knob on the DLC clockwise to zero the pump. It will be difficult to
rotate as you are back-driving the DLC motor. Be careful! Do not force the knob. Try turning it in
both directions to get a feel for the back-drive torque. As you approach zero the knocking will
diminish.
5. Once you have found zero, mark the knob and cover with a piece of tape to use as a reference.
6. You can set the stroke adjustment to a specific value by calculating the number of knob turns. To do
this, divide the desired setting (%) by a factor of 4(%/rotation). For example, say your desired setting
was 67%. You would divide 67 by 4 which equals 16.75. So you would turn the knob 16 and 3/4
revolutions from the zero position.
