DC Power Supply
Three types of isolated DC power supplies are available to sup-
ply an external transmitter or sensor. These are 20V rated at
25mA, 12V rated at 40mA and 5V rated at 80mA. The DC volt-
age is delivered to the output 2 terminals.
Caution:
To avoid damage, don’t use a DC power supply beyond its
current rating. Purchase one with the correct voltage to suit
your external devices. See the ordering code in section 1-2.
3–22 Manual Control
Manual control may be used for the following purposes:
1. To test the process characteristics to obtain a step response as
well as an impulse response and use these data for tuning a
controller.
2. To use manual control instead of a closed-loop control if the
sensor fails or the controller’s A-D converter fails. NOTE that
bumpless transfer can not be used for an extended time. See
section 3-17.
3. In certain applications, it is desirable to supply a process with
a constant demand.
Operation:
Press until
(hand control) appears on the display.
Press for 3 seconds, then the upper
display will begin to flash and the lower
display will show . The con-
troller is now in manual control mode.
Press ; the lower display will show
and alternately where
indicates output 1 (or heating)
control variable value MV1 and indicates output 2 (or
cooling) control variable value MV2. Now you can use the up and
down keys to adjust the percentage values for H or C.
The controller performs open loop control as long as it stays in
manual control mode. The H value is exported to output 1
(OUT1) and C value is exported to output 2 provided that OUT2
is performing cooling function (i.e., OUT2 selects COOL).
Exception
If OUT1 is configured as ON-OFF control (i.e., PB1=0 if PB1 is
assigned or PB2=0 if PB2 is assigned by event input), the con-
troller will never perform manual control mode.
Exiting Manual Control
Press keys the and the controller will
revert to its previous operating mode (may be a
failure mode or normal control mode).
Means
MV1=38.4% for
OUT1 (or heating)
Means
MV2=7.63% for
OUT2 (or cooling)
