5.13 “Soft Start” FUNCTION

At power up, the instrument will measure the

process variable and compare the measured value

with a programmed threshold (see P10 parameter

in chapter 4).

If the measured value is lower than the pro-

grammed value, the instrument will limit the

maximum output power (see OLH operative

parameter) for a programmed time (see tOL

operative parameter).

If tOL is equal to InF, the limiter is ever active.

MEASUREMENT ANOMALY SIGNAL

The instrument display (the upper display for model

1603E) shows the OVERRANGE and UNDERRANGE

conditions with the following indications:

Overrange Underrange

The example shows the display of model 1603E.

Model 1601E displays 4 digits.

The sensor break can be signalled as:

- for TC/mV input : OVERRANGE or

UNDERRANGE selected by

a solder jumper

- for RTD input : OVERRANGE

On RTD input, a special test is provided to signal

OVERRANGE when input resistance is less than 15

ohm (Short circuit sensor detection).

NOTENOTE

NOTE:

When:

- The instrument is set for one control out only and

an OVERRANGE is detected, the OUT 1 turns

OFF (if reverse action) or ON (if direct action).

- The instrument is set to use two control outs and

an OVERRANGE is detected, OUT 1 turns OFF

and OUT 2 turns ON.

- The instrument is set for one control out only and

an UNDERRANGE is detected, the OUT 1 turns

ON (if reverse action) or OFF (if direct action).
