NOTE 2: When the battery is recharging, the screen will indicate ‘charging’. Once the battery is full, the screen will indicate ‘charged’.
the outer 2 red LED’s illuminate for a period of 14 hours, after which are replaced by green LED’s. This is a timer function only, not an indication of the charged condition of a battery. 16

17. Alarms
All gas ranges have alarm limits that trigger an alarm when the measured value exceeds the set level
The audible alarm sounds, LEDs flash red, the instrument vibrates and the gas range in alarm flashes on the display
Flammable LEL Alarm Limits - Up to 2 alarm levels are programmable
Over-Range Flammable Gas Alarm - If the flammable gas readings exceed 120% LEL, a safety alarm is activated
Oxygen Alarm Limits - Up to 1 upper and 2 lower alarm limits are programmable
Toxic Alarm Limits - Up to 2 instantaneous and 2 Time Weighted Average (TWA) alarms are programmable for each toxic range
NOTE: A Time Weighted Average value is the mean average gas level over a specific period. The STEL is 15 minutes and LTEL is 8 hours. UK legislation requires the TWAs to be averaged over a 24 hour period whether the instrument is On or Off. Such averaging essentially makes the instrument single user applicable. An option is to restart the averaging at each switch-off, allowing for multiple user application. 17

18. The instrument display will signal the range in alarm.
Alarms (2)
The instrument display will signal the range in alarm.
Example of Lo Lo Oxygen Alarm Display
Example of HiHi LEL Alarm Display
In the 1st example the Lo Lo Oxygen Alarm is activated. 2 lower alarm limits are programmable in the oxygen range, these could be 19% and 18%. This display shows the instrument having measured an oxygen level below the 2nd of the low alarm limits.
In the 2nd example the HI HI LEL Alarm is activated. Typically, the HI HI LEL would be set at 20%, a 2nd higher limit can be set if required. 18

19. Alarms can be latching or non-latching
Latching - alarm will stay on until the user resets by a press and hold of the RH button when the gas level return to within the pre-set alarm limits
Non-Latching - the audible and visual alarm will reset automatically when the reading returns to within the pre-set alarm limits 19

20. Acknowledging Gas Alarms
Once in a safe gas free area, or the gas reading has returned to within pre-set limits, press and hold the RH button to acknowledge/clear the alarm sounder and extinguish the red LED’s.
Alarms can have the mute function enabled or disabled
Once in a gas free area, or the gas reading has returned to within pre-set limits, a press and hold of the RH button will silence / mute the sounder and extinguish the LED’s.
Mute Enabled in set-up - silences alarm for 60 seconds
Mute Disabled in set-up - cannot silence alarm until gas falls below alarm level
Acknowledging Gas Alarms depends on the set up configuration of these alarms. PS 200 has a totally flexible set-up to conform to the user required for latching, non-latching, mute enabled, disabled. Please refer to your individual company guidelines regarding gas alarms. 20

21. Alarms (5) Muting Gas Alarms
Alarms can have the mute function enabled or disabled
This means the audible alarm can be silenced for 60s.
If the alarm is non-latching, after 60s it will operate according to the gas concentration at that moment. I.e. if safe, it will remain silent, if above alarm level it will start sounding again.
If the alarm is latching, after 60s the audible alarm sounds again, regardless of the concentration. The user can then mute it again (if the concentration is above the alarm level, or acknowledge it if it is below).
Once in a gas free area, or the gas reading has returned to within pre-set limits, a press and hold of the RH button will silence / mute the sounder and extinguish the LED’s.
Mute Enabled in set-up - silences alarm for 60 seconds
Mute Disabled in set-up - cannot silence alarm until gas falls below alarm level
Acknowledging Gas Alarms depends on the set up configuration of these alarms. PS 200 has a totally flexible set-up to conform to the user required for latching, non-latching, mute enabled, disabled. Please refer to your individual company guidelines regarding gas alarms. 21

22. High Flammable Gas Over-Range Alarms
Protects the user from danger in event of the LEL sensor being over exposed to a high concentration of flammable gas
When over 120% LEL has been detected, the displayed value will change to four rising arrows, tone of audible alarm will change and a flashing message will be shown
The instrument must be returned to a gas free area and switched off by a press of both buttons together. A timer from 10 to zero will appear with the messages below alternating
The high flammable gas over-range alarm is designed to protect the user from danger. It is also worth noting that exposing the LEL sensor to concentrations of flammable gas above 100% LEL can damage the sensor.
NOTE: To avoid accidental switch off in a dangerous state, the off cycle is increased to 10 seconds 22

23. Default Alarm Settings (Table 1)
