DataView™ LI55 Level Controller

Instruction Manual

Signal Connections

Signal connections are made to a six-terminal connector labeled

SIGNAL on Figure 7. The COM (common) terminal is the return for the 4-20 mA

and the 10 V input signals.

Current and Voltage Connections

The following figures show examples of current and voltage connections. T

here are no switches or jumpers to set up for current and voltage inputs. Setup and

programming is performed through the front panel buttons.

Most Common Wiring

The current input is protected against current overload by a resettable fuse. The

display may or may not show a fault condition depending on the nature of the

overload.

The fuse limits the current to a safe level when it detects a fault condition, and

automatically resets itself when the fault condition is removed.
