Model UP350 program controller is a precision controller,
featuring two program profiles and universal input/output.-
For easy operation, it is provided with a large display for
process variables, two program operation keys, and a
program reset key. For excellent controll, auto-tuning, PID
control with the “SUPER” overshoot suppressing function
and the "SUPER2" hunting suppressing function are
available. It also has a retransmission output and 15V DC
loop power supply as standard.
■Main Features
• Extra-large digital display allows the indicated values to be
read even from a long distance. LEDs of 20mm height are
used for the process variable display.
• It can store two program pattern types. Programmed
operation can be started by using the two program
operation keys on the front panel and terminated by using
the reset key.
• Universal input and output enable users to set or change
freely the type of measured inputs (thermocouple, RTD, or
DCV), measurement range, type of control output (4 to 20
mA current, voltage pulse, or relay contact, etc. from the
front panel.
• Parameters can be easily set using a personal computer.
("Parameter setting tool (model LL100)" sold separately is
required.)
• Various communication function are provided.
Communication is possible with personal computer,
programable logic controller, and other controllers.

■Function Specifications
● Program Setting Function
“Program setting” allows the controller's target setpoint to
increase or decrease along the program pattern versus time.
The instrument, provided with two program patterns, can be
operated by using the front panel key or through the external
contact. One program pattern consists of 10 broken lines
(program segments). If the two program patterns are
combined, a program pattern of up to 20 segments can be
created. The length of each segment can be specified by the
segment time. Users can also configure the number of
repeats, event outputs, etc.
Number of program patterns: 2
Number of segments/pattern: 10
Number of program repeat: Unlimited repeats
Segment time: 0 min. 0 s to 99 min. 59 s, or
The function to delay the progress of a program pattern if the
process variable (PV) has not reached the target setpoint
(SP). The wait zone is the deviation band of acceptable PV
response is determined, and the wait time is the time to wait
for the PV to reach the wait zone. If the PV reaches the wait
zone within a certain time (the wait time), then the program
will advance to the next segment. If it does not reach the wait
zone after the wait time has elapsed, then the program will
eventually advance to the next segment.
Wait time: 0 min. 1 s to 99 min. 59 s, or
0 h 1 min. to 99 h 59 min.
Wait zone: OFF, 0.0 to 10.0 % of measured input range
width.

Program Setting Function and PID Parameter
Switching
PID parameter switching in accordance with the progress of
the program pattern is available.
Zone PID: PID parameter selection according to the
Reference point method:
Reference point = Measuring input range (0%)
Reference point hysteresis = Fixed to 0.5% of the
Reference deviation method:
Reference deviation = OFF, 0.1 to 100.0% of
Measuring input range (100%)
Measuring input range (0%)
value of the PV is available. Reference point
(setpoint for PID parameter switching) or
reference deviation is used for switching.
Up to two points can be set to divide the PV
range up to three zones, and this selects the
PID parameter set (PID 1 to 3) according to
zone.
Reference point 1 Reference point 2

unstable due to hunting, etc. without requiring
any change in PID constants, when the load
and/or gain varies greatly, or when there is a
difference between the characteristics of
temperature zones.

15V DC Loop Power Supply
The controller supplies power to a two-wire transmitter.
Place a resistor (10 to 250 Ω, optional) between the controller and the transmitter, convert a current signal to a voltage
signal, and read it from the PV input. Either the retransmission output or the loop power supply can be used.
Supply voltage is 14.5 to 18.0 V DC. Maximum supply
current is about 21 mA (with a protection circuit for a field
short-circuit).
The control output is of a universal scheme and can be
selected from the following types of outputs.
