System Operation and Configuration
The setup of the controller is critical for proper operation. Modbus™ addresses must be correct on all the
devices connected to the controller before the controller will acknowledge them. The number of sensors
must be entered into the controller to allow it to communicate with them. Four basic areas need to be
configured:
¾
The number of sensors must be determined before setup begins.
¾ The sensor’s channel information must be configured to match the sensor connected.
¾ Relay modules and banks must be configured.
4.1 Operator Interface
The operator interface of the CXT controller is accomplished via four internal magnetic switches located
above the controller’s backlit LCD display. The four switches offer a non-intrusive interface and allow for
complete configuration of the controller. These switches are labeled: PROG, “u” (Up Arrow), “v” (Down
Arrow) and ENTER. The ENTER switch also doubles as a RESET/ACK switch from the Main Display
only (Not in Menu Mode). With reference to the Menu Flow Chart (See Figure 10), it is easy to learn how
to navigate the menus and make changes.
The magnetic programming tool (See Figure 8) is used to operate the magnetic switches. Switch action is
defined as a momentary contact (hold) on a switch marker (
⊗). For momentary contact, the programming
magnet is briefly held on the switch marker ( ⊗) and then removed. This action will be referred to as a
“swipe” for the remainder of this manual.

4.1.1 PROG Switch
From the Main Display, the PROG switch enters into the Main Menu. Once inside the Main Menu, the
PROG switch acts as an “Escape” switch that moves backwards in the menu flow chart.
NOTE: While in Main Menu mode there are no updates to gas readings and hence no alarms
will take place.
4.1.2 “u” Up Arrow Switch
This switch moves the user up the Main Menu flow chart. It is also used to change selected entries
within menu selections in the upward direction.
4.1.3 “v” Down Arrow Switch
This switch moves the user down the Main Menu flow chart. It is also used to change selected entries
within menu selections in the downward direction.
4.1.4 ENTER and RESET/ACK Switch
This switch has multi-purpose use. The ENTER function is used to accept selections within all menu
screens. The switch is also used to execute the Reset and Acknowledge functions. The Reset function
releases all latched relays if they have cleared the alarm/fault condition. The Acknowledge function
will disengage any silenceable relays that are in a currently active state. This is typically used to
