First Time Switch On - Honeywell Series 3000 MkII Technical Manual

SERIES 3000 MKII TECHNICAL MANUAL

7. First time switch on

After mounting and wiring the transmitter, the plug in sensor should be fitted and the installation visually
and electrically tested as below.
Prior to carrying out any work ensure local and site procedures are
followed. Ensure that the associated control panel is inhibited so as
Minimum and maximum controller alarm levels should not be set at less
than 10% or greater than 90% of the full scale range of the detector.
Caution: The following procedure should be followed carefully and only performed
1. Check that the transmitter is wired correctly according to this manual and the associated control
equipment manual.
2. Unscrew the weatherproof cover, loosen the sensor retainer locking screw and unscrew the retainer.
3. Plug in the sensor taking care to align the sensor pins with the connector holes in the pcb.
Caution: For toxic sensors, remove the shorting clip from the bottom of the sensor
prior to installation. For O2 sensor, there is no shorting clip provided.
4. Refit the sensor retainer, tighten the locking screw and refit the weatherproof cover.
5. Apply power to the associated controller which will in turn provide power to the detector.
6. The detector output will be forced to 3mA (default fault / inhibit).
7. The detector display will enter a start up routine first displaying all the LCD segments and symbols, then
the transmitter loads the data from the sensor and checks if it is the same type transmitter and sensor
software version numbers, gas type, the detection range and span calibration gas level, estimated
time to next calibration due, self test result, and finally warm up period shown as a countdown to 0.
(Countdown time varies from 30 seconds to 3 minutes, depending on the sensor type).
8. Once countdown is complete, the detector will enter normal 'monitoring' mode.
Note: Calibration is mandatory before the detector can be used for gas monitoring. Refer to Section
8.2 Calibration for the proper procedure.
WARNING
to prevent false alarms.
