[METHOD 2: USING THE UP/DOWN BUTTONS TO SELECT TIME]
DO NOT apply a signal when programming Delay Times using Method 2 in Sequence Mode.
(1) Depress and release the “MODE SELECT” button until “DELAY TIME” L.E.D. is lit.
(2) Depress the UP button for 1 second and release.
(3) Depress and release the PROGRAM/PRIME switch of the pump # to be programmed.
(4) Depress and release the UP button to select the desired delay time. Using this method of programming, the
delay time can be programmed in MINUTES ONLY. The KDC timer will display the delay time in minutes. When
the KDC timer display returns to “000", the input time has been stored.
(5) Repeat steps 3 and 4 for each pump to be programmed. Do not program a pump to run more than one time
during a “sequence”.
•
EXECUTING RUN TIMES
If the input signal is removed for 3 minutes, and reapplied, then the “run” sequence will begin from the first pump
programmed. The pumps will execute their programmed run times in the sequence in which they have been
programmed. If the input signal is removed for less than 3 minutes, and reapplied,
then the program halts, and time
is not counted down. The “programming” sequence will then continue from the input signal interruption point, when
the input signal is reapplied.
RELAY MODE OPERATION
More and more machines today contain their own microprocessor controls which can operate chemical injection
pumps. In “Relay Mode”, signals received for each pump activate that pump as long as the signal is active. No
programming is required. To select Relay Mode, move the jumper located above the RELAY, SIGNL, and SEQ L.E.
D.’s to jumper terminals located above the RELAY MODE L.E.D. (JP6). Upon receipt of a pump activation signal
from the machine controller, the corresponding pump will run. The pump will run as long as the signal is present.
There is no signal verification delay (5.1 seconds) in relay mode.
Typical laundry installations utilize incoming and outgoing supply lines for each chemical that might be injected into a
wash machine. These supply lines, over a period of time, suffer from chemical breakdown caused by the supply
products that flow through them, and may clog or break. A flush manifold assembly flushes liquid laundry supply
tubes with water after supplies have been injected into the machine. The flush manifold can be used in Signal and
Sequence modes only.
FLUSH VALVE METHOD OF OPERATION
While a liquid chemical is being injected into a manifold, water is simultaneously injected into the manifold. After the
chemical injection is complete, the manifold will continue to be flushed with water for a programmed amount of time.
ENABLING THE MPL-1000 PLUS FLUSH VALVE
(1) Move the jumpers on the upper left-hand corner of the board to FLUSH. Because the MPL-1000 uses pump #6
as the flush output, ensure that the load count jumpers are not set to count off of pump #6.
(2) Connect the wire from the solenoid coil to the pump #6 terminals on the MPL-1000. ENSURE THAT THE
VOLTAGE OF THE COIL MATCHES THE VOLTAGE OF THE MPL-1000 BOARD.
(3) The flow switch of the flush valve assembly is designed to ensure flow of water. Connect the flow switch to the
FLUSH SWITCH terminals on the MPL-1000 board located inside the pump housing. If it is not desired to
monitor the flow of water, connect the FLUSH SWITCH terminals together on the MPL-1000 board. Connect a
24 VDC buzzer to the BUZZER terminals of the MPL-1000 board. This buzzer will sound when a “flush error”
takes place (see step #5).
