P-Power Save Set Point

To turn on the Power-Save
1
feature, do one of the following
tasks, never do both:
• either press all three keys ( ,
, and ) simultaneously, or
SET
• install an external switch to close
contacts #3 and #4 on the rear
terminal strip.
When the control is operating in
Power-Save mode, the display will
alternately change between the
process value and three dashes ---.
Return to normal SP1 operation
2
with one of the following tasks:
• either press all three keys ( ,
, and ) simultaneously, or
SET
• switch OFF the remote switch
wired to terminals #3 and #4.
To view the
3 P SET POINT
press once and release. The
control will display the letter P and
a decimal point followed by the
numeric
P SET POINT
To change the Set Point value,
4
press while the
SET
value displays (value will flash).
Once the value flashes, press
5
or to change the value.
Press once to lock the new
6 SET
value into memory.

Alarm Set Point

Enable the Alarm feature. See
1
Configuration (Setup), F3 Alarm
On/Off Switch for instructions.
Press twice and release. The
2
letter , followed by a decimal point
A
and the Alarm Set Point value
displays. (After a few seconds the
screen returns to normal.)
To change the
3
press while the alarm Set Point
SET
value still displays (value will flash).
When it flashes, use

Calibration

This section includes calibration
procedures for 2 & 3 wire RTDs,
Resistance, Voltage, Current Input,
Frequency, and Thermocouples.
Warning!
Calibration procedures require the
removal of the rear cover of the
control. It also requires that power is
ON, exposing the technician to
potentially lethal voltages. Always
Exercise EXTREME CARE and wear
tested electrician's gloves when power
is on.

2 Wire RTD

RTD devices are precision resistors
whose resistance value varies with
temperature. DQ15D measures RTD
resistance and compares that value
with a standard set of values stored
in memory. You can restore, update
or verify that this standard set of
values is correct.
Equipment needed
• Two precision resistors (tolerance
+/- 0.1% or better) with a fixed
value equal to the RTD nominal
value (i.e. 1000 ohms).
• A suitable jumper cable to
facilitate changing input
resistance.
