3 Wire System and 4 Wire System

System Input (IQ 330 and IQ 330M only)
The System Input displays the accumulated counts of the two digital inputs and the
value of the 4 to 20ma analog input. The digital inputs count the positive and
negative edges of a square wave signal. The signal must have an amplitude greater
than 12 volts and will be clamped at 50 volts. The counts will roll-over the display at
65535. The counts can be tracked to 4294967295 via INCOM and the MODBUS
pass through commands before roll over occurs.
The 4 to 20ma analog input will be represented as 0 to 100 percent on the display.
4.6.4
System Lock (IQ 330 and IQ 330M only)
The lockout feature is unique to the IQ 330 type models. The feature is a physical
shaft or button protruding from the top of the base. The shaft has a hole in it so the
wire tamper proof seal can be employed to disable it. The feature is a toggle. Press
the button and the unit will be locked. Press the button again and the unit will be
unlocked.
While in the locked state changes to setup and reset values (listed below) will be
denied. When a user tries to change any of the values in the list below an ERROR
TRY AGAIN message will appear. Simple unlock the IQ 330 to access these
functions.
