Instructor Unit
Operation
The Instructor Unit is operated by means of four buttons.
It features the same optical and auditory alarms as the Student
Unit does. Almost all settings of the system are made via the
Instructor Unit, which sends these to the Student Unit via a
wireless link.
Connector, controls and indicators of the Instructor Unit:
(1) Optical alarm and charger indicator (front)
(2) Optical alarm (top)
(3) LCD Display
(4) Power button
(5) Charger connector
(6) Mode button
(7) Up button
(8) Down button
Switching on
-
Press the Power button (4) briefly.
The device will switch itself on and give a short optical signal (3,4) and a short beep. The device will start
up and shortly show the LION logo on the display (5) (figure 3.8).
The device will then automatically switch to measuring mode.
Four measurements are shown:
•
Lower Explosion Limit (%LEL)
•
Oxygen (O
2
)
•
Hydrogen Sulfide (H
2
S)
•
Carbon Monoxide (CO)
The transmitter symbol (shown at “%LEL in figure 3.9) shows which measurement is responding on the
transmitters.
The arrow symbol (shown at “%O2” in figure 3.9) shows which measurement is currently selected to be
adjustable manually using the up and down buttons.
The wireless communication channel and internal battery level are shown on the right.
The Instructor Unit will continuously search for a Student Unit at the selected channel.
If a Student Unit is present, the puppet symbol will show on the left side of the display. The battery under
the puppet symbol gives information about the Student Unit’s battery level.
If no Student unit is present, both the puppet symbol and the left battery symbol are not shown.
