1. INTRODUCTION
The W4-2 scales controllers provide all the functionality required to
implement a mobile or fixed weigh scales solution in the NOMAD system.
The standard controller accepts up to four load cells.
Power is supplied by internal rechargeable batteries and charger with a
universal voltage range is built in.
2. OPERATION - W4-2
There are two modes of operation - operator and supervisor mode.
Operator mode is the default state of the scales and is the mode where
actual weighing takes place - the only action that may be performed in
operator mode.
Supervisor mode is protected by a keyswitch or nominated ID tags. It is in
this mode that operators are clocked in and out and all other functions are
performed.
All numerical entries should be followed by pressing the ‘ENT’ key.
Pressing the ‘CLR’ key will clear the current entry with subsequent presses
backtracking up the menu hierarchy if any.
2.1 OPERATOR MODE
In operator mode the controller waits for an operator number.
Place the load onto the weigh platform. Note that the weight is not
displayed until the reading is accepted.
Enter the operator number. The controller will check to see if the operator is
known to the controller - that is they have clocked in and have not clocked
out. If the entered operator number is known to the controller then it will
prompt for a row number.
