OPERATION (AUTO MODE)
AUTO MODE
Both the AP6 and AP8 series pumps have an optional
auto-start controller (MS-200). This controller allows for a
float switch capability which is designed for the automatic
start-stop of the pump. Additionally, audible and visual alerts
signal engine restarting through a control box alarm and
beacon attachment.
MSS 200 AUTO START CONTROLLER
The MSS-200 is an automatic engine start stop controller.
The MSS-200 is fully programmable. Its 15 parameters
are pre-programmed at the factory to the most commonly
used parameters. Changing the factory preset, however, is
easily accomplished by pushing three buttons (Figure 24)
on the front of the face of the controller.

Automatic Shutdowns
When used in combination with ground contact switches,
the MSS-200 can also shutdown the engine. The control
box allows for the wiring and automatic shutdown of the
engine for the following parameters:
„ High Oil Pressure 150 psi (1,034 kPa)
„ High Coolant Temperature 220~230°F (102~112°C)
„ Alternator Charge
„ Broken V-Belt
„ Engine Overspeed
„ Other Customer Defined Parameters
NOTICE
The MSS-200 is a dual function controller, meaning it
can be used for generator or pump applications. When
programming the various operating parameters use
pump related parameters only (pump mode).

FLOAT SWITCHES
Two pairs of normally open float switch contacts (high/low)
are provided with the auto-start controller. The controller is
pre-wired for the floats, utilizing a 4-pin connector located
at the rear of the control box.
PARAMETERS
Preheat Parameter
The duration period of preheat can be programmed by time
(in 4 second increments) or by ambient temperature if used
in combination with a PT-1000 thermistor or equivalent.
The preheat time setting, has priority over ambient
temperature. In case of a defective thermistor or loose
wire connection, it is important that a time value is always
programmed when used in combination with a thermistor.
When using the temperature thermistor provision, use
Table 9 for temperature verses time comparison.
The preheat function on the MSS-200 can also be used in
combination with a pre-start audible alarm. Simply program
a preheat duration and add an alarm to the preheat output
to provide additional safety to your equipment. Alarms are
available as an option.
NOTICE
Refer to the programming section of this manual
when changing any of the factory preset parameters
is required.
