General Description:
The Motion Alarm circuit monitors the Roller Apparatus to verify the continuous motion of the
roller shafts. Should the motion stop an alarm indicator will illuminate on the front panel and
an audible alarm will sound.
Operation:
The alarm circuit is shown working by the blinking yellow / green l.e.d.
, labeled “MOTION
SENSOR
” located on the front panel – see figure 4. The blinking yellow / green l.e.d. indicates
the circuit is receiving pulses from the sensors. If a pulse is not received within 2 ½ minutes,
then the alarm is triggered. The red l.e.d. is illuminated
– labeled “MOTION ALARM”, an 85 dB
audible alarm is sounded, and the “REMOTE ALARM OUTPUT” relay is switched.
The “ALARM SILENCE” push button is also located on the front panel – see figure 4. When
the alarm has been activated, pressing this button will silence the audible alarm, turn off the
ALARM l.e.d. and switch the Alarm Output relay. The alarm circuit remains off until it is reset.
The circuit may be reset by cycling the power or re-establishing the roller motion.
