Once you have your sensor(s) positioned and connected properly, the system is ready for continuous
operation. Operation is accomplished either through the back panel or through controlling software.
A setup and configuration program is supplied with your sensor. You can also create custom
programs using the communications protocols listed in Section 9 Programming Guide on page 44.
6.1 Control Panel
The sensor is equipped with a control panel, which has setting/controlling buttons and an LED
display. The panel is used primarily for setting up the instrument and is covered over during normal
use.
The control panel is protected by the supplied end cap. The sighting hole in the end cap is threaded to
accept the polarizing filter accessory (used for sighting/focusing on very bright targets). An end cap
with a larger window, which allows all control panel LED’s to be visible, is available as an option.
(You cannot use the polarizing filter with this option.)
You can configure sensor settings with the control panel or with a computer. The panel is used
primarily for setting up the instrument. The buttons and LED’s are defined in the following sections.
Figure 20: Control Panel
The sensor has a remote locking feature that keeps the unit from being accidentally changed from the
control panel (locked by default in multidrop mode). This lockout mode denies access to all the
switches on the control panel. It is available through the RS485 connection and can be unlocked only
by a command from the remote computer.
On the sensor’s back panel is a switch that is labeled “S” and “A.” Make sure the switch is always in
the “A” position, the “S” position is for servicing only.
