Installation And Electrical Connection - Wilo Control SC-Fire Diesel A2P Installation And Operating Instructions Manual

"AUTO MODE 1/2" (Fig. 2, pos. 30, 31)
The green LED turns on if the corresponding key switch is in the "Auto" position. In the automatic mode, the
automatic start-up of the diesel motor is possible either via the intermediary of the float switch or the
corresponding pressure switch.
"NON-AUTO MODE 1/2" (Fig. 2, pos. 32, 33)
The green LED turns on if the corresponding key switch is in the "0" or "Manual" position. In the non-automatic
mode, no automatic start-up of the diesel motor is possible via the intermediary of the float switch or the
corresponding pressure switch.
"START-UP VIA PRESSURE SWITCH 1/2" (Fig. 2, pos. 34, 35)
The control lamp flashes green as soon as the pressure of the unit drops below the set/requested pressure and
when pressure switch 1 or 2 is triggered. Once the start-up delay has elapsed (menu 1.2.5.1), the control lamp
is permanently turned on. If the pressure increases as a consequence, the control lamp turns off once again. If
the key switch 1 or 2 is in the "Auto" position, the diesel motor starts automatically. If the pressure increases
and the output button (Fig. 2, pos. 20) is activated (level of access 2 required), the indicator light turns back on.
"PRESSURE SWITCH LINE 1/2 MALFUNCTION" (Fig. 2, pos. 36, 37)
The connection of the pressure switches is monitored. Any short-circuit or cable rupture is signalled by the LED
turning on red. If the corresponding key switch is in the "Auto" position, the diesel motor starts up automatically.
Even in the absence of problems, the number of start-up attempts is limited to 6.
