Control mode
CTL
UP150 has two control mode.
Select one from the following:
a. PID control (PID)
b. On/off control (ONF)
Manual reset
MR
You can set this parameter only for control
without an integral action (when registered as
CTL=PID and I=OFF). The controller outputs the
manual reset (MR) value when PV=SP. For
example, if you set MR=50%, the controller
outputs (OUT) 50% when PV=SP.
Hysteresis for
PV evnets 1 and 2
HY1,
HY2
The PV events are output as relay outputs. Since a
relay has a limited service life, excessive on/off
actions will shorten the life of a relay. To prevent
this, you can set a hysteresis band for both PV
evnets 1 and 2 to moderate excessive on/off
actions .
DI-function
selection
DIS
• When DIS=ON, Mode can be switched by only
external contact input signal.
• In order to switch the Mode by key operation,
OFF must be set at DIS.
Note: UP150 can be switched into “RESET”
mode by key operation even if DIS=ON.
SUPER
function
selection
SC
The SUPER function is effective in the following cases:
a. An overshoot must be suppressed.
b. The rise-up time needs to be shortened.
c. The load often varies.
Note 1: The SUPER function will not work when
on/off control is selected, or I or D
constants is set at OFF in PID control.
Note 2: For some types of systems, the SUPER
function may not be so useful. If this is
the case, turn off the function.

EOF1

The time event feature begins countdown when a
program starts running, and after the elapse of a
preset time, output an on-time event signal
(contact output ON) or off-time event signal
(contact output OFF).
Hysteresis for
on/off control
HYS
For on/off control (CTL=ONF), you can set a
hysteresis around the on/off point (SP) to prevent
chattering.
On/off point (Program SP)
Hysteresis
ON
OFF
The cycle time is the period of on/off repetitions of
a relay or voltage pulse output in time proportional
PID control. The ratio of the ON time to the cycle
time is proportional to the control output value.

CT
PV input bias
BS
This function adds a bias value to the measured
input value, and the result is used for display and
control computation.
This function is useful for carrying out fine
adjustment when the PV value is within the
required accuracy but it differs from the value
obtained by other equipment.

PV input filter
FL
This function should be used when the PV display
value may fluctuate greatly, for example, when the
measured input signal contains noise. The filter is
of the first-order lag type, and FL sets the time
constant. If a larger time constant is set, the filter
can remove more noise.

input
DP
For DC voltage input, the input signal can be scaled for the
particular engineering unit. For example, if you set the input
type (IN) at range code 22, the initial range is 0.0 to 100.0.
a. Using DP, set the decimal point position fit for the
engineering unit you want to use. (In the example below,
the 2 digits to the right of the decimal point)
b. Next, register the scale values of the measured input scale using
RH and RL. (In the example below, RH=10.00 and RL=0.00)
