The corresponding alarm LED and relay will remain activated until the cause of the alarm or fault is clear.
Latching Mode
The relay can be deactivated after the alarm condition has cleared by acknowledging the Alarm Reset
function on the front panel of the X40 controller or by activating the external reset switch if installed
(Section 7.0).
Non-Latching Mode
The relay is deactivated as soon as the sensor alarm or fault condition is clear.
1.8 System Operation
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 the devices. Each wireless
sensor must have a unique Modbus address (refer to sensor manual for details). The number of sensors is
determined during auto configure if the addresses on the sensors and modules are set correctly.
The operator interface of the X40 utilizes four internal magnetic switches located above the controller’s
backlit LCD display.
The four switches provide a non-intrusive interface and allow for complete
configuration of the controller and are labeled as follows:
• PROG,
•  (Up Arrow),
•  (Down Arrow) and
• ENTER.
The ENTER switch also doubles as a RESET/ACK switch from the Main Display only (not in Menu
Mode).
