3.1: Security Input
The security input is often referred to as the “Run/Program” input. This input is located on the 16-place
terminal strip and is discussed in Chapter 6: Security Inputs. This input prevents unauthorized changes
to the programmed functions. With the unit in the “Program” mode, all functions of the controller can be
programmed. With the unit in the “Run” mode, all setpoints, reset-to-preset, motion detect and other
operational functions can be verified, but the programmed information cannot be changed.
3.2: Initialization
The following key commands should be entered on the
keypad to clear all programmed data upon installation and PRIOR to programming. This sequence
clears all programmed data. All operating parameters must be reprogrammed after using this initializa-
tion function.
3.3: Scale Factor
NOTE: Programming of the desired scale factor or the number of outputs will delete all programmed
data held in memory. Therefore, these should be the first steps in your setup procedure.
The 1995L Valid Scale Factors are 2 to 1,000.
To program the scale factor, the following procedures must be followed:
1) Unit must be in the “Program” mode.
2) Depress - Desired Scale Factor -
NOTE: Display will read from 0 to 1 less than Scale Factor.
