MAINTENANCE
AS10-D Amplifier
The AS10-D Amplifier is shipped with two replacement AGC1, fast
blowing, 250V, 1A fuses. The replacement fuses are located to the
left of the main printed circuit board (See Fig.12).
AWL280 Sensors
The sensor's detection sensitivity is reduced when paper dust or
other material gathers on the lens of the AWL280 Sensor. The
sensor alarm relay changes state and the LED on AS10-D front
panel that is labeled "Detector Dark" will turn "ON". Gently wipe
the dust from the surface of the lens and take care not to scratch
the lens surface. See Figure 6 for wiring information. Refer to the
Calibration section for setup.
