Parameter Reset Features
On initial power up, all parameters are at "original" values. In many cases, when a
Parameter Value is altered, associated Parameter Values are automatically
altered accordingly. When a Parameter Number is accessed, if the preset
Parameter Value displayed is acceptable, no entry is required.
To return an operator adjusted Parameter Value to the preset value, with the
appropriate Point Number and Parameter Number displayed press
To reset numerous parameters to preset values, refer to Master Reset (P999).
Note:
Perform a Master Reset (P999) if the DPS300 was "bench tested" using arbitrary
Parameter Values before system installation, following an EPROM replacement,
or whenever complete reprogramming is required.
Special Parameters
Some Parameter Values are for display purposes only and cannot be operator
altered. These are referred to as view only parameters. In the parameters sections
of this instruction manual, View Only parameters are identified by a "(V)" beside
the Parameter Number.
Some Parameter Values must be common for all Point Numbers. These are
referred to as global parameters. When a global parameter is accessed, the Point
Number display automatically switches to Point Number 00, and returns to the
Point Number previously selected when a non-global parameter is accessed. In
the parameters sections of this manual, Global parameters are identified by a
"(G)" beside the Parameter Number.
Programming Security
All operator programming is retained in non-volatile memory, immune to power
interruptions. When programming is complete, the programmer may be removed
and locked away to prevent inadvertent programming alteration. As well the Lock
(P000) parameter may be used.
Security Parameter: P000 (G) Lock
Use this feature (if desired) to secure all programming from inadvertent alteration.
"Direct access" this parameter (it cannot be scroll accessed) after all programming
is complete and enter any value (other than 1954) to activate the programming
Lock.
When Lock is activated, the DPS300 may be switched from the RUN mode to the
program mode and the value of any parameter may be viewed but not altered. To
unlock, access this parameter and enter the value "1954".
This parameter cannot be reset by pressing
Values:
1954 = off (Parameter Value alteration permitted)
other = activated (programming secured)
