Chapter 2 - Introduction
Low Limit Controller
When the PV input signal is above the limit set point, the output relay
energizes. If the PV signal falls below the limit set point, the output
relay de-energizes and the flashing "LIMIT" display is turned on.
When the PV signal returns to a value above the limit set point, the
controller can be reset manually using the RESET key or Contact
Input Option.
Easy to read displays
The dedicated vacuum fluorescent displays with multi-language
prompts make the operator interface easy to read, understand and
operate. Programmed sequences of displays assure quick and
accurate entry of all configurable parameters.
Easy to operate
Simple keystrokes let you select input and range configuration, set
the operating parameters that meet you process control needs now,
and change them later to meet new ones.
Mount anywhere
This instrument is intended for industrial control applications. It
must be panel mounted with the wiring terminals enclosed within the
panel. The instrument is environmentally hardened and, when
suitably enclosed, can be mounted anywhere in plant or factory, on
the wall, or even on the process machine itself. The front face is
NEMA3 and IP55 rated and can be easily upgraded to NEMA4X and
IP66 for the most severe hose-down applications. It withstands
ambient temperatures up to 55°C (133°F) and resists the effects of
vibration and shock.
