Battery voltage, behaviour of the PRX
Battery voltage, behaviour of the PRX
The following table contains a brief description of the LED and / or the PRX.
LED
Status
Flashes green directly after switching on Flashing code for battery type
Constant green
Voltage above ‘Charge battery’ (all OK)
Flashes green
‘Charge battery’ (land now)
Flashes red / green
A brief voltage collapse to below ‘Low voltage’
has occurred (shorter than four seconds)
Constant red
‘Low voltage’ (land immediately)
Flashes red, low rate
Battery flat
Flashes red, high rate
Battery defective
Flashes red / green, high rate
Input voltage excessive
The following table shows the behaviour of the PRX and / or the LED in response to various input
voltages (i.e. battery voltage). The table shows a typical response to a battery as it is discharged,
commencing at excessive voltage. The table should be read as follows: “Battery voltage higher /
lower than that stated: PRX responds by ...”
Status
Voltage
Response
More than 9V
Both LEDs flash red / green, fast *
More than ‘Charge battery’
LED constant green
Less than ‘Charge battery’
LED flashes green
More than ‘Charge battery’
LED constant green
Less than ‘Low voltage’
LED flashes red / green (stored)
More than ‘Low voltage’
LED flashes red / green (stored)
Less than ‘Low voltage’ for more than 4 sec.
LED constant red (stored)
More than ‘Low voltage’
LED constant red (stored)
Less than 4.3V
LED flashes red, slow (stored) **
More than 4.3V
LED flashes red, slow (stored) **
Less than 3.3V
LED flashes red, fast (stored) ***
More than 3.3V
LED flashes red, fast (stored) ***
Less than 3.3 V for more than 2 sec.
LED and device switched off.
* The input voltage may be present at the output for one second; after this the output is
switched off.
** Battery flat.
*** Battery defective.
