PULSAR MEASUREMENT
33
By default, the 4-20 mA will represent the operational span of the dBi model
in use, with empty (0% full) = 4mA and full (100% of the operational span) =
20mA, but you may wish to only represent a section of the operational span.
For example, the application may have an operational span of 6 metres, but
you may only wish to represent empty level to 5 metres. If so, change
P834
(Low Value) to 0 , and P835 (High Value) to 5.0.
If the device connected to the mA output is out of calibration, and cannot be
calibrated, then the low and high current levels can be trimmed by altering
P838 (Low Trim) and P839 (High Trim) . To do this, simply enter the value
that ensures that 4 mA or 20 mA respectively are shown on the remote
device. You can use the left/right menu keys to alter the value until the
correct reading is shown on the remote device, rather than typing in a value.
Setting Security Passcodes
A passcode is used to protect parameter entries and will be required when
accessing parameters with certain PC Software’s. You can set a new
passcode to prevent anyone changing any of your settings within your dBi
Series Intelligent Transducer. The default
passcode is 1997 , but this may be
changed as follows.
Changing the Passcode
You can set the passcode to any number from 0000 to 9999. To do this,
select P922 which is the Passcode parameter which can be changed as
required.
Resetting Factory Defaults
If you need to restore parameters to their original factory settings, then
access parameter
P930 , which is the factory defaults parameter, change the
value to 1 and ENTER , all parameters, except for the mA trims, will be
restored to the factory settings (including the DATEM trace) and on
completion.
Important Notice
The passcode is also used for remote access using certain PC Software’s,
so if this is being used, be sure to ensure any additional equipment using
this feature is changed accordingly.
