Storage Limits: –40 to 70°C (–40 to 158°F).
RELATIVE HUMIDITY
10 to 90%, non-condensing.
VOLTAGE AND FREQUENCY
Universal power supply: 90 to 250 VAC, 48 to 62 Hz.
NOISE IMMUNITY
Common mode rejection (process input): >120 dB.
Normal mode rejection (process input): >80 dB.
AC line is double filtered and transient protected. Snubbers are
provided for each relay output.
CONSTRUCTION
Case: extruded, non-perforated black anodized aluminum with ABS
plastic sleeve.
Bezel: black plastic ABS.
Chassis assembly: plug-in type.
Keys: silicone rubber with diffusion printed graphics.
NEMA rating: front panel conforms to NEMA 4X when instrument is
properly installed.
AGENCY APPROVALS
R
LR 84603
Memory Retention
Lithium battery maintains all programming for
approximately ten years.
Security
There are two levels of access: restricted and full.
A configurable code is used to enter the full
access level. Functions not available in the restricted level
are configurable.
DIGITAL INPUTS
A set of five external dry contacts or open collector transistor driven
inputs are available. Each can be configured to perform one of the
following functions:
• Select remote setpoint •Select either direct or reverse
• Select manual control
control action
• Select second local setpoint •Disable adaptive tuning
• Select a second set of •Addressable through serial
PID values communications only
• Acknowledge alarms •Inhibit the reset term
• Simulate ▲ and ▼ keys •Lock controller in manual mode
• Simulate DISPLAY, FAST •Select PV1 or PV2
and MENU keys
In addition, if the set of five digital inputs is installed, four may be
designated to select one of eight local setpoints (and associated PID
set, if desired) via a binary coded decimal (BCD) input.
SETPOINT SELECTION
A remote setpoint input is available. Signal is 0–20/4–20 mADC or
0–5/1–5 VDC (jumper selectable). Signal may be ratioed and biased.
Eight local setpoints may be stored in memory.
Setpoint selection is made via SET PT key or digital contact(s).
FAULT OUTPUT
One of the alarm outputs may be designated to also energize if
the input signal is lost.
SERIAL COMMUNICATIONS
Isolated serial communications is available using an RS-485
interface. Baud rates of up to 19,600 are selectable. The protocol
supports CRC data checking. If communications is lost, a time-out
feature will command the controller to a particular control mode
and specific setpoint or output if desired. Outputs 2–4 and digital
inputs can act as “host-controlled” I/O independent of the
controller’s function. The PV may be sourced via this interface.
May be installed in the field.
DIGITAL DISPLAYS
Upper display: five-digit, seven-segment. Used exclusively for
displaying the process variable value. Height is 15 mm (0.6 in.).
2nd display: nine-character, 14-segment alphanumeric. Used for
displaying setpoint, deviation, output value, slidewire position
(actual valve position) and configuration information. Height is
6mm (0.25 in.).
3rd display: nine-character, 14-segment alphanumeric. Used for
indicating which loop is displayed and for displaying alarm
messages and configuration information.
Height is 6mm (0.25 in.).
All displays are vacuum fluorescent. Color is blue-green.
STATUS INDICATORS
There are two types of indicators: icons and illuminated keys.
ALM 1 and ALM 2 icons: alarm 1 and alarm 2 status.
OUT 1 and OUT 2 icons: control output 1 and control output 2 status.
MAN key illuminated: controller is in manual control mode.
ACK key illuminated: alarm may be acknowledged.
SET PT key illuminated: setpoint other than primary local setpoint is
active.
MENU key illuminated: controller is in configuration mode.
