ZGARD CX II Controller 
Start-Up Procedure 
 
When  wiring,  checking  or  working  within  a  ZGARD  CX  II  Controller,  always  disconnect  the 
main power to prevent bodily harm. 

 

1.  Loosen the locking screws on front of the controller and open the door.  

2.  Locate the power switch on main circuit board inside controller enclosure. 

3.  Check all wiring connections are correct and secure. 

4.  Confirm  the  RS485  digital  remote  sensors  associated  with  the  controller  are  appropriately  assigned  a 

unique binary address code. 

Refer to the appropriate gas sensor manual for further details. 

 

5.  Power up the controller and observe the behavior of the following indicators; 

Green LED (SYSTEM OK) Indicator on front panel should be ON.  

Red LED (SYSTEM FAULT) Indicator on front panel should be OFF. 

Amber LED (CAUTION) Indicator should be OFF 

Amber LED (WARNING) Indicator on front panel should be OFF.

  

Red LED (ALARM) Indicator on front panel should be OFF. 

During initial power up of the controller, the local audible alarm may be activated, press RESET button 
to silence.  

 

6. 

Allow the associated remote gas sensors to stabilize. 

Refer to the ZGARD S or GS sensor manual for 

further details.  

 

Depending on the controller’s warning, alarm and delay settings, the display status and the relay action 
of the controller may vary. Refer to the installation sections of the associated ZGARD CX II Controller. 

 

7.  Confirm  the  functionality  of  the  controller  and  that  is  operating  according  to  the  designed  or  pre-set 

configuration settings. 

 

8. 

Apply  a  representative  sample  (at  least  60%  of  the  operating  range)  of  the  target  gas  to  each  of  the 
associated remote gas sensors. This simple test should drive  the  gas sensors upscale and simulate a 
warning and or an alarm condition on the controller. 

Refer to the ZGARD S or GS sensor manual for 

further details.   

 

During this procedure, the audible device may be activated, press RESET button to silence.  
The warning and alarm indicators and the corresponding relays may be activated. 

Depending on the controller’s warning and alarm set-points and delay feature settings, the Warning and 

Alarm relays may be activated.  

Any  remote  equipment,  which  may  be  connected  to  the  controller  relay  contacts,  should  now  be 
activated.  

 

9.  Remove any test equipment from the sensor and controller. 

10.  Secure the locking screws on the front door of the ZGARD CX II Controller. 

11.  Secure the locking screws on cover or front door of the associated remote gas sensors.  

 

The initial function test of the ZGARD CX II Controller is now completed.
