Control Unit Status Indicators

POWER APPLIED TO MACHINE CONTROL SYSTEM
Before intervention, turn off and disconnect power from FF-LS Series safety light curtain and machine.
Failure to comply with these instructions could result in death or serious injury.
The control unit has seven status indicator LEDs (see below). The green status LEDs 1, 2 and 3 are always illuminated if
the supply voltage is present. The yellow status LEDs 4 and 6, the red status LEDs 5 and 7 and a buzzer (acoustic signal)
are used to determine the operational status of the safety equipment. This buzzer (acoustic signal) can be switched on or off
using the buzzer switch located on the control unit printed circuit board (see figure 5-2).

Method
• Insert a 30 mm or 14 mm diameter test rod into
the light curtain sensing field and ensure the
machine stops.
• Test function generated by the machine (closing
an external normally open contact located in the
"test loop" of the FF-LS control unit)
• Count the machines cycles and evaluate the
number of operations.
• Visually inspect enclosure to ensure the control
unit is closed and locked. The key should be
kept by an appointed person.
• Visually inspect the safety light curtain and the
electrical wiring to ensure that they are in
serviceable condition.
• Use a clean, soft, dry cloth for dust removal.
• Use a clean, soft cloth with soapy water for
grease removal.
• Wipe without rubbing (rubbing causes streaks
and static electricity that attracts dust).
• Products used to clean windows may be used.
• Never use solvents like petrol, white spirit,
trichlorœthane, trichlorœtylene, or acetone.
Frequency
Daily, at each power up, and after each
intervention (or maintenance)
performed on the protective safety
equipment
Each time the machine is used or as
part of each cycle
1,000,000 operations (1.5 A/220 Vac,
1.5 A / 24 Vdc) or every 3 years if
protective RC elements are mounted
