The MPD delay is set by applying a slotted screwdriver to the adjuster, K4, located on the relay at
the extreme left of the bottom bracket. It is factory-set to 30 seconds, but can be adjusted to
between 2 to 180 seconds. This same timer also detects the time between pulses, so that a
pulser that malfunctions after fueling has started will also actuate the MPD circuitry. Every pulse
resets the timer to zero.
The MPD option also serves as a key reminder alarm. After fueling is complete, and the pulser
stops, the alarm will sound (and power relay open) within the pre-set time (nominally 30 seconds).
This relay may be bypassed by a toggle switch located on the upper left portion of the bottom
bracket.
START DELAY (SD)
Not available on Split Dual Pump Control Units. The GASBOY Electric Keytrol is supplied with an
additional time delay relay that provides a delay on initial turn-on. The delay is adjustable from 3
to 180 seconds. It has been factory set for 3 seconds. Just like the missing Pulse Detector (MPD)
relay, it can be set by the owner to the time desired. See figure below for the location of the
different relays.
Upon actuation of a key, there will be a three second delay before power is applied to the Electric
Reset in the pump or dispenser. Consequently, the register will reset to zero after this delay time
and the fuel can then be dispensed. However, rapid switching of the key will not turn the pump on
and off. It is suggested that the time be set for three seconds to minimize customer
inconvenience. However, to prevent excessive product losses, set the time to ten seconds or
greater.
This relay may be bypassed by a toggle switch located on the upper left portion of the bottom
bracket.
