7.3 COMMUNICATIONS

7.3.1 DESCRIPTION OF COMMUNICATIONS

The Sentry controller scans each channel in turn taking

less than one second to scan all channels. At each channel:

1.A "reset" signal is sent out to clear all module communications.

2.An address (which is a module number) is sent out and the controller waits for a response. The response is a digital frequency which is proportional to the first of eight parameters which are interrogated by the controller.

3.Because the controller received an answer and knows that the particular module is on that channel it continues to interrogate that module to retrieve the remaining seven parameters before moving to the next module number.

The eight (total) signals are:

∙Value of Ground.

∙Value of sensor signal (relates to gas concentration).

∙Heater voltage (Type 1 Module) or Bridge Voltage (Type 2 Module).

∙Heater current (Type 1 Module) or Bridge Current (Type 2 Module).

∙Sensor type (Type 1 through 4 Modules).

∙Calibration switch condition on/off.

∙Module voltage (tests line drop from controller to module).

∙Reference voltage (used together with ground to ratiometrically compensate for any temperature drift in module components)

The controller interprets the information received during the polling and takes actions as necessary. (Any deviation from normal is rapidly validated to avoid errors due to

electrical noise.) The information, combined with continual system diagnostics allows the controller to accurately determine abnormal conditions. Table 7-1 provides a categorized listing of Sentry messages.
