5 Powering Up
ENSURE SAFE WIRING PRACTICES ARE FOL-
LOWED
The instrument must be powered from a supply ac-
cording to the wiring label on the side of the unit. The
supply will be either 100 to 240V AC, or 24/48V AC/DC
powered. Check carefully the supply voltage and con-
nections before applying power.
When powering up for the first time, discon-
nect the output connections.
Powering Up Procedure
At power up, a self-test procedure is automatically
started, during which all LED segments and indicators
are lit. At the first power up from new, or if the option
modules are changed, Goto Conf will be displayed, in-
dicating configuration is required (refer to section 6).
At all other times, the instrument returns to operator
mode once the self-test procedure is complete.
Overview of Front Panel
The illustration below shows a typical instrument front
panel. Refer to the following table – Typical LED func-
tions for a description of the front panel indicators.
Each model in the range will vary slightly from the ex-
ample shown.
Displays
Controllers are provided with a dual line display and
LED indicators for mode, automatic tune, alarm and
output status. The upper display shows the process
variable value during normal operation, whilst the lower
display shows the Setpoint value. See the preceding
diagram - Typical front panel and keys.
