Pump operation
7.5.1
Motor Start/Stop, Speed control
The vehicle engine can be started from the remote control
pendant using the push button (Item 4, Fig. 7.20). This can
only be done if the key switch (Item 14, Fig. 7.6) on the
control panel desk is set to “Remote Control”.
Pressing the push button (Item 5, Fig. 7.20) stops the vehicle
engine, and inhibits its restart for approx. 10 sec.
Pressing the rocker switch (Item 7, Fig. 7.20 or Item 9, Fig.
7.21) brings the vehicle engine from idling to full speed
within 10 sec.
7.5.2
“Pump/Suck” control at the control
panel desk
The operating mode selection switch (Item 14, Fig. 7.21)
must be set to “Desk”. The rocker switch (Item 11, Fig.
7.21) selects “Pump” or “Suck”. For confirmation one of
the two indicator lamps (Item 10 or 12, Fig. 7.21) will light.
The stroke rate depends on the setting of the stroke rate
potentiometer (Item 13, Fig. 7.21) and the engine speed.
NOTE:
Opening the safety grill or pressing an Emergency Stop button (whilst the
“Pump/Suck” switch is activated), will deactivate the “Pump/Suck” function.
NOTE:
If the hydraulic oil temperature exceeds 80
°
C, the pump function is stopped
and the indicator lamp (Item 4, Fig. 7.21) on the control panel desk will light.
Sucking the concrete back remains available. The hydraulic system must be
cooled down as quickly as possible by appropriate means (see section 7.6.4).
