Start - Up
8.1. Setting up the detector
Start the «Prism Targeting»mode by moving the operating mode switch (see Fig. 3.)
up (if the detector is mounted vertically) or to the right (if the detector is mounted
horizontally).
Connect the power supply.
The detector runs in initialization mode for approx. 5 s.
As soon as the detector is ready for use, the red LED flashes (once with the Fireray
50RV and twice with the Fireray 100RV).
Now direct the detector at the prism, using the two knurled screws, until optimum
adjustment is confirmed by a steady yellow LED light. The following LED displays
support detector set - up:
Yellow LED display
Detector status in «Prism Targeting» operating mode
off
No signal at receiver
Flashes
- > Flashing frequency in-
creasing
Signal is received
- > The faster the flashing, the stronger the signal!
Steady light
Optimum alignment achieved
The signal must only move from the reflector to the receiver,
under no circumstances must it move to other light sources or
reflective surfaces!
Cover the prism reflector with a non- reflective material to check. The LED must not
be lit. If the yellow LED does not go out, this indicates that a reflector is incorrectly
aligned.
8.2. Calibrating the detector
Once the optimum detector set - up has been achieved, set the operating mode
switch to the center position without displacing the detector. The detector is now in
(«Alignment Mode»).
The detector runs through an automatic configuration procedure to optimize the
transmission power and the receiver sensitivity. The following detector statuses
may be displayed by the LEDs during this procedure:
LED displays
Detector statuses in «Alignment Mode»
Flashing red
Receiver input signal too strong, the transmission power will be re-
duced. Wait until the LED goes out (max. 20 s).
Steady yellow light
No signal is being received. Switch back to «Prism Targeting» mode
and repeat the detector set - up.
Flashing yellow
The receiver is receiving a weak signal, the transmission power will
automatically be increased.
off
Transmission power and receiver gain are optimum.
Flashing red and yellow
Automatic calibration in progress.
