Wilo -Control SC-Fire Diesel DK Installation And Operating Instructions Manual page 30

• Manual start of battery A and battery B
(Fig. 2, items 16 and 17)
Pressing the button starts the diesel engine manu-
ally via battery A or battery B. The starter is ac-
tive as long as the button is pressed. Once the mo-
tor has started, it can only be stopped by pressing
the "stop" button.
• Manual stop (Fig. 2, item 14)
This button is used to stop the motor. If the rele-
vant signal lamp (Fig. 2, item 14) lights up red
when the motor is running, the motor can be
stopped. The motor can only be stopped if there is
no request from the pressure switch present
(sprinkler request). Once the motor has stopped,
the signal lamps for "pump in operation" and
"stop" go out (Fig. 2, items 2 and 14).
• Test device for manual starter device
(Fig. 2, item 13)
Test button and signal lamp for regular inspection
of the manual electric starter device. The button
becomes functional if an automatic motor start
was followed by a manual switch off, or if six
consecutive automatic start attempts are unsuc-
cessful. In both operating statuses, the signal lamp
lights up and the button has to be pushed.
• Lamp test (Fig. 2, item 15)
Pushing the button switches on all the signal lamps
for as long as the button is pushed, allowing you to
check that the lamps function. When you release
the button, the signal lamps go out again and only
light up according to their regular operation.
• Acknowledgement (Fig. 2, item 18)
Pressing the button resets all the error messages or
signal lamps provided that the cause of the error
no longer exists.
6.2.3 Switchgear display elements
Operational standby (Fig. 2, item 1)
The signal lamp lights up green when the power
supply is connected.
Pump operation (Fig. 2, item 2)
The signal lamp lights up green when the diesel
engine has started and the speed recorded by the
Speed transmitter has reached or exceeded the
value set for "motor in operation" (menu 1.2.1.3).
Automatic mode (Fig. 2, item 3)
The signal lamp flashes yellow when automatic
mode is switched off (menu 3.1.0.0).
Excess motor temperature (cooling water)

Oil pressure fault (Fig. 2, item 5)
The signal lamp lights up yellow when a connect-
ed oil pressure monitor is triggered.
False start (Fig. 2, item 6)
The signal lamp lights up yellow after six consec-
utive unsuccessful automatic start attempts.
Sprinkler request (Fig. 2, item 7)
The signal lamp lights up white if the pressure in
the system falls below the set/requested pressure
and at least one of the two pressure switches is
triggered. Once the start delay has expired
(menu 1.2.5.1), the signal lamp lights up continu-
ously. If the pressure rises accordingly, the signal
lamp goes out.
Float switch request (Fig. 2, item 8)
The signal lamp flashes white when the level in
the pump priming tank falls to 2/3 and the float
switch is triggered. Once the start delay has ex-
pired (menu 1.2.5.2), the signal lamp lights up
continuously. If the level rises accordingly, the
signal lamp goes out.
Heating fault (Fig. 2, item 9)
The signal lamp lights up yellow when a connect-
ed thermostatic valve is triggered.
Belt break (Fig. 2, item 10)
The signal lamp lights up yellow when a belt
break is detected.
Belt break (Fig. 2, item 11)
The signal lamp lights up yellow when the fuel
float switch is triggered.
Collective fault (Fig. 2, item 12)
The signal lamp lights up red when a fault occurs.
The fault must be acknowledged when its cause
has been rectified.
Test device for manual starter device
(Fig. 2, item 13)
The signal lamp lights up if an automatic motor
start was followed by a manual switch off, or if
six consecutive automatic start attempts are un-
successful.
Manual pump stop (Fig. 2, item 14)
The signal lamp lights up red as soon as the stop
function for the stop button is enabled when the
motor is running. The stop function is not enabled
when the pressure switch (sprinkler request) has
been triggered.
