Read and observe this manual prior to installation and start-up. The Statox 503 Control Module is only allowed to operate under the given ambient conditions (see Technical Data). In particular, it must not be operated in potentially explosive atmospheres! The Statox 503 Control Module must be operated, maintained and repaired by trained and expert ... - Page 5 Zone 1 or 2. The Statox 503 can also be operated as Common Alarm Module. It collects the alarm signals (A1/A2/SF) of up to 25 connected control modules and generates a common alarm on LEDs, relays and its analog output.

Page 7: Dismounting
Statox 503 Control Module You can combine modules of the Statox 503 series in any sequence. Adding or removing one module has no impact on the others. You can save wiring effort starting with the power supply on the outside and connecting it to the bus with the bus plug. -
Page 8: Connecting To Power Supply
Otherwise the sensor can be damaged. Ex works the Statox 503 is configurated to operate as Control Module. After connection to power, it performs a self-test. It displays the firmware version, then for 5 seconds the actual measuring program, then “PLEASE WAIT”. - Page 9 Statox 503 Control Module If a sensor head has been connected and the appropriate program has been selected, the measuring mode will start. Sensor heads for combustible gases, type HRC, ARE, LC IR, MCIR, CO and PID must be calibrated after being connected.
