Alarm strategy

Two soft alarms for PV, deviation high/low/absolute. A
special loop alarm is also provided to detect faults in
the control loop by continuously analyzing the PV
response to the control output. Alarm inhibit is
available on power up and setpoint switching.

Manual/Automatic mode

Manual control (via bumpless transfer) is enabled by
simply pressing the front-face AUTO/MAN key. The
“SET” LED flashes and the output power is displayed
on the lower display. Output can be adjusted with the
upper and lower keys.

Pre-tuning and self-tuning strategy

Pre-tuning is used to set up the PID parameters close
to the optimum values, which the self-tuning algorithm
uses to subsequently optimize the tuning parameters.

Limit controller

Packaged in 1/16 DIN, the UDC1200 limit controller is
designed to provide a safety shut-off and optional
alarm for use in a wide variety of applications.

Highly secure

A non-volatile memory based on EEPROM technology
ensures data integrity during loss of power supply, with
retention of more than 100 years. A 4-digit security code
prevents unauthorized or accidental change.

Upper display: 4 characters
dedicated to show the PV.
In configuration mode, it shows
the parameter value or selection

Lower display: 4 characters
dedicated in normal operation
mode to display the SP. In
configuration mode, it displays
the

arameter name.

Up to three outputs

The UDC1200 and UDC1700 provide up to three
outputs for time and current proportioning, duplex
mode (heat/cool), PV or SP retransmission, and
alarms.

Setpoint ramp

The current setpoint can ramp to a new-targeted
setpoint by way of a user defined ramp rate.

Dual setpoint

Dual setpoint option is available on the UDC1200 and
UDC1700. The current setpoint is selected by a digital
input. This option is exclusive with UDC1200 limit

Physical Description

The UDC1200 controller is housed in a 110 mm (4.33
inches) deep case with a standard UDC gray bezel. It
can be mounted in a 1/16 DIN panel cutout.

The UDC1700 controller is housed in a 100 mm (3.94
inches) deep case and can be mounted in a 1/8 DIN
panel cutout. By using the pre-assembled mounting
fixture delivered with the unit, you can easily and
securely install the controller into the panel cutout.
Modular plug-in construction allows rapid access and
saves time. All inputs and outputs are connected on
the rear terminal block by screws.

Operator Interface

Four display combinations are offered to the operator.
The upper 4-digit 7-segment display is always
dedicated to monitor the PV. The lower display can
show:

 SETPOINT (read only)
 SETPOINT (adjustable)
 RAMPING setpoint (ramp mode)
 BLANK

Universal Inputs

All input types are available on any unit. Selection
among the various types of inputs is made by prompt
configuration. As soon as the Process Variable
reaches the value of the input range limit, the controller
displays a message. A sensor break indication is also
provided. A configurable digital filter is available from

0.5 seconds to 100.0 seconds.

Outputs

Three types of outputs (RELAY, SSR driver or DC linear)
are selectable for three outputs, through the model selection
guide or by adding a plug-in module for outputs 1, 2 and 3.

Outputs Algorithm

The UDC1200 and UDC1700 are available with the
following output algorithms:

 Time proportional:

ON/OFF or time proportional with
electromechanical relay SPDT 2 A or SSR driver
(open collector).

 Current proportional:

Supply directly proportional current or voltage
signal to the final control elements which require 0­20 mA, 4 20 mA, 0-10 V or 0-5 V.

 Time proportional duplex:

Three duplex modes can be selected, either
ON/OFF duplex, time proportional duplex
(heat/cool with two proportional bands, two cycle
times and deadband) or TPSC.

 Current proportional duplex:

In addition to the first current/voltage output, a
second similar output with its own proportional
band is provided.

 Current/Time or Time/Current duplex:

Provides a variation of traditional time or current
duplex mode by mixing current and time
proportioning together.

Control Algorithms

Four control algorithms can be set up through the
configuration menu:

 On/Off  PID
 PD + MR  TPSC

The TPSC (Three Position Step Control) control algorithm is
dedicated to control valve positioning without slidewire
feedback from the motor shaft.

Configuration

There are two levels of configuration. The SET-UP
mode allows modification of current parameters such
as tuning parameters, alarm values, setpoint limit,
ramp enable, auto-manual mode enable and auto­pretune enable.

The CONFIGURATION mode is more oriented to unit
personality: input selection, output 2 and 3 usage,
alarm type, communication address and lockout code.

The operator mode screens are only selectable via the
configuration software only. For instance, the alarm
value screen can be moved from setup mode to
normal operator mode if desired.

Control Mode

Manual or automatic mode with bumpless transfer is
standard feature. In manual mode, the operator can
directly control the output through the two front face
keys (raise and lower keys). The output value is
monitored on the lower display.

Alarms

Outputs 1, 2 and 3 can be used as alarms. Two
electromechanical single pole double throw relays can
activate external equipment when alarm setpoints are
reached. An LED is also activated on the front-face. A
direct or reverse acting alarm output can be
configured. A logical combination of the two alarms:
OR, AND or hysteresis (active when both alarms are
active and inactive when both alarms are inactive) can
be set which associates the two alarms status before
energizing the relay. In order to detect a defective
control loop, the controller can supply special loop
alarm control by continually monitoring the PV
response to output demand. A timer is automatically
set up when any output is on saturation mode. When
the timer reaches twice the reset time with no PV
response, the loop alarm is activated. With this soft
alarm there is no need for a heater circuit breaker,
saving wiring time and costs.

Limit Controller

The UDC1200 1/16 DIN limit controller provides a latched
relay output which is activated when the process parameters
either exceed or fall bellow the desired value, providing a
failsafe cut-off which has to be manually reset before the
process can continue.

The UDC1200 limit controller can be configured to be either
a “high limit” unit where the delay will de-energize when the
PV is above the limit setpoint, or a “low limit”, where the
relay will drop out when the PV falls below the setpoint.

A LED indicator shows when limits have been exceeded,
and when the relay is latched out.

The optional digital input allows a remote reset function.

Remote Setpoint Model

The UDC1700 1/8 DIN "R" model controller has a second
input available that accepts either a linear or potentiometer
input signal as a remote setpoint. The input signals
accepted are field-configurable and are: 0-5 V, 1-5 V, 0-10
V, 2-10 V, 0-20 mA, 4-20 mA (factory set), 0-50 mV, 10-50
mV, 0 100 mV, or 0-2000 ohms. This allows the controller
to act as a "slave" controller accepting a setpoint value from
a 'master' device such as a PLC or setpoint-programming
controller (such as the DCP50, DCP100, DCP300, or
DCP550 series).

The UDC1700R also includes a standard digital input
allowing remote switching between the local setpoint and
the remote setpoint value. Also standard in this model is
"fuzzy" autotune software that minimizes process variable
overshoot when responding to a setpoint change.

PC Software

The UDC1200 & 1700 are supported with PC software
allowing you to quickly configure your device using
configuration wizards, or to perform diagnostics.

Display

Dual, four-digit LED display with decimal point location
configurable up to three places for linear ranges only.
