Parameter Reset Features
On initial power up, all parameters are at default 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
Index and Parameter Number displayed press CLEAR and ENTER
.
To reset all parameters to preset values, use Master Reset (P999).
Parameters Types
View Only Parameters
Parameter values indicating status only. They cannot be altered.
Global Values
Parameter values common to all inputs and outputs on the SITRANS LU01.
When a global parameter is accessed, the index display automatically disappears. When
a non-global parameter is accessed, the index display reappears showing the last index
number.
Parameter Indexing
To set all indexed values for a parameter to the same value, use index 0.
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. Use the Lock (P000)
parameter to secure the SITRANS LU01.
Note: Perform a Master Reset (P999) if the SITRANS LU01 was bench tested
using arbitrary Parameter Values before system installation, following an EPROM
replacement, or whenever complete reprogramming is required.
