To return an operator adjusted Parameter Value to the preset value, with the
appropriate Point Number and Parameter Number displayed press
, .
To reset all parameters to preset values, refer to Master Reset (P999).
Note:
Perform a Master Reset (P999) if the SPL 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 (cannot be scroll accessed) this parameter after all programming is
complete and enter any value (other than 1954) to activate the programming Lock.
When Lock is activated, the SPL 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, direct access this parameter and enter the value "1954".
This parameter cannot be reset by pressing
.
Values:
1954 = off (Parameter Value alteration permitted)
-1 = control relays active during simulation
other = activated (programming secured)
