Switch On; Initial Configuration - Honeywell Unipoint 2306B1000 Operating Instructions Manual

UNIPOINT OPERATING MANUAL 2306M5001 MAN0638 ISSUE 7 01/2011

6 Switch On

After connecting power, the controller enters a self test routine: All LCD segments flash, the
fault and alarm LED flash, the sounder operates three times, the RAM, ROM and EEPROM are
checked and the software version is displayed. If no faults are found (see section 7.5 for fault
codes) the unit enters a detector warm up period indicted by a count down from 60 to 0 on the
display. During this time the controller is inhibited ('Inh') so all alarms and faults are inactive.
At the end of the warm-up period the controller checks for detector and field wiring faults. If a
fault is found, the fault code is displayed (see section 7.5 for fault codes). If no fault is found
the controller enters normal operation and will display current gas reading and alarm(s) if
appropriate.

7 Initial Configuration

WARNING
Unipoint must be zero and span calibrated with the detector
before operation.
If the default configuration shown in section 5.1 (mV type controller) or 5.2 (mA type controller)
does not match the application requirements, follow the procedures below to reconfigure the
controller.
Notes: If using a mA version controller with a 3 wire mA type detector, carry out the
procedure in section 7.1 first to set the correct detector type.
If configuring the controller for use with an Oxygen detector, skip the 'Set zero' instructions
(steps 7-14) and use 20.9% (background air oxygen level) as the span calibration point.
After completing all the steps in a menu, the 3 button must be pressed to save the changes.
Press x at any time to ignore the changes made in the current menu.
1. Press the st buttons together to enter the configuration mode.
2. Press 3 to enter the 'Set Range and Units (FS)' menu.

7. Press the t button to select the 'Set Zero (0)' menu.
8. Press 3 to enter the 'Set Zero (0)' menu.
9. The current zero gas reading is displayed.
10. Apply zero gas to the detector.
11. Press 3 when the reading is stable.
12. The display will show '---' while calculating the zero point and then '0' when complete. If
the zero fails 'FFF' is displayed.
13. Remove the zero gas from the detector.
14. Press 3 to complete the zero calibration.
15. Press the t button to select the 'Set Span (S)' menu.
16. Press 3 to enter the 'Set Span (S)' menu.
17. 50% of the set range flashes.
18. Press st buttons to set the concentration of the span calibration gas concentration
being used.
19. Press 3 to set the span calibration concentration.
20. Apply the span calibration gas to the detector.
21. The 'live' gas reading is displayed.
22. If the reading is too low 'S-L' is displayed, if too high 'S-H' is displayed.
