SITRANS LU01 – INSTRUCTION MANUAL

7ML19985BE02

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). 

Parameter values indicating status only. They cannot be altered. 

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.

To set all indexed values for a parameter to the same value, use index 0.

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. 

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.
