Lamp check (Alert action check)
When the warning lamps are off, there is no trouble on each function. If thewarning lamp(s) is on or blinking, the pump does not work properly.
NOTE

Turning on the power, the warning lamps and buzzer will be
activated for approximately one second. (The lamp check isautomatically performed and the installed computer starts
monitoring.)

Throttle position is controlled to low pressure
position (Engine revolution goes down.), and then
the throttle does not work.
OverheatIn the case of engine temperature reaches thesetting temperature of approximately 80 C,
warning buzzer intermittently sounds and thewarning lamp turns on.

Overheat warning lamp

In the case of the engine temperature exceeds
90 C, warning buzzer sounds, warning lamp turns
on and the engine stops automatically.
In the case of engine temperature exceeds 120 Cor higher, warning buzzer sounds and the warning
lamp turns on. Even in this situation the starter
motor can work but the engine does not run.
Suction failure

Suction failure lamp

When the water suction cannot be completed within
30 seconds, the warning lamp of suction failureturns on and the engine will stop.

3. USE OF REMOTE CONTROL PANEL
NOTE

If the throttle position is at lower position (at about Idle position)
than “ ” position, the vacuum pump will not start automatically.
If the starter motor does not operate although the throttle is at the“ ” position, check if the battery terminals are tightly connected
and the battery is fully charged.
If the engine does not start in five time starting operations,eliminate the cause of failure, then start the engine.
VE1500A-Ti pump control panel does not have the engine runningstatus lamp and the discharge water status lamp.

3) Discharge waterOpen the discharge valve(s). Checking pressuregauges, adjust the discharge pressure by pressing“ ” or “ ” switch.
While discharging water, wherever the throttle
position is, by pressing the suction water position
switch “ ” or low pressure position switch“ ”, thethrottle position will turn to “ ” or “ ” position.

4) Stop the engine
Decrease the discharge pressure by pressing theswitch “ ” or “ ” until the throttle turn to low
pressure position.
Close the discharge valve(s).
Press the stop switch to stop the engine. At thesame time, lamps on the panel turn off. (Powerturns off)

4. STARTING THE ENGINE
Operating VE1500A-Ti is possible with both of the pump control panel and the remotecontrol panel.
Connect the remote control panel to the operation panel of pump (VE1500A-Ti).

94. STARTING THE ENGINENOTE

The throttle position turns to the low pressure position after
completed of sucking water at automatic suction water mode justafter the power on.
When the engine starts, the engine running lamp turns on.
When the starter motor runs for a long time continuously, thepower of the battery will be exhausted quickly. The maximum time
for starting motor operation is 3 seconds at one time. If the engine
does not start up, wait for 5 seconds before operating the starter
motor again.
If the starter motor does not work, check that the battery terminals
are tightly connected and the battery is fully charged.
If the engine does not start in five time starting operations,eliminate the cause of the failure, then start the engine.
Starting the engine at the throttle position of “ ” or higher, theengine speed will be controlled to be maximum 3000 rpm due to
avoid over-speed of vacuum pump.

<In the case of just only starting the engine with remote control panel>
After turning on the power, press "Start switch / Low pressure switch“ ”", then only the engine will start, vacuum pump will not start. (If the throttle
position is under “ ” position, starting the engine may not be easy in coldcondition.)
CAUTION

If running the engine with no water, the engine will overheat.
Suck up water as soon as possible to avoid overheating.
Maximum running time with no water is follows*,
Idling: Within 2 minutes
Throttle dial at “ ” mark position: Within 30 seconds* As a reference (depending on ambient temperature).

<Sucking up priming water after engine starts>
After starting the engine, press the throttle
position switch “ ”. And then the vacuum pumpruns until sucking up the water completed.
Discharge water status lamp will turns on after
sucking up water completed.
NOTEMaximum vacuum pump operation
time at one time is 30 seconds.
