The heart of each 1000 Series dispenser is the EFD advanced solid-
state, digital timer with programmable time ranges and choice of
Momentary (press the foot pedal once) or Maintained (hold foot
pedal down during time cycle) initiation modes.
This unique timer is located inside the dispenser. To access, remove
the two cover screws and slide the cover off the dispenser.
Caution: Always disconnect the power cord before removing the
cover.
The DIP switch that controls the timer has been set at the factory for
a time range of 0.01 to 1.0 second, with the initiation set to
MOMENTARY contact. (See top diagram.)
Experience shows this is the most often used initiation mode and
time range.
For larger deposits that require longer time, it may be advantageous
to set the initiation to MAINTAINED contact. The operator must then
keep the foot pedal pressed throughout the time cycle.
Four time ranges are provided so that you can have fine-time
adjustment in the range you select.
For extremely small dots of low viscosity, watery fluids, you may want
to select the 0.005 to 0.04 second range. For slow filling, a longer
time range will provide the time that's needed for flow control.
