IMPORTANT:
This data is calculated with a 16.5 Ah battery. This is a certified Intrinsically
Safe device and the battery recommended by the manufacturer complies with the conditions of
certification. Use of a type of battery other than that specified by the manufacturer will
compromise the Intrinsically Safe certification. OPW-FMS, Tokheim/Pro Gauge or Start
Italiana cannot be held responsible for equipment failures or safety issues related to use of an
non-certified battery.
More information on the battery can be found in the section
"Important Battery Information" on the next

LED Behavior
There are two (2) LEDs inside the probe that give important status information.
GREEN LED:
The GREEN LED shows the status of the probe's float detection.
l
GREEN LED flashes quickly: This is an indication that the probe is in normal operation.
l
GREEN LED flashes slowly: The probe cannot detect the float. This could be caused by:
n
A missing float
n
The float was installed upside-down
n
A bent probe shaft
n
A damaged float
RED LED:
The RED LED identifies the status of serial communication.
l
RED LED is OFF: No data is received on the serial communication RS485 port.
l
RED LED is ON: Serial communication is received but the probe address is not read.
l
RED LED is ON then turns OFF: Three (3) seconds of timeout has passed without any serial
communication or the probe has been addressed and it is in reply.
NOTE:
The polling cycle and frequency as well as the number of probes installed on the
same bus will have a direct effect on the RED LED behavior.
