SECTION 1: PRODUCT DESCRIPTION
1.1 General
This instrument is a microprocessor based single loop controller capable of measuring,
displaying and controlling temperature, pressure, flow, and level from a variety of
inputs. Most outputs are easily tuned using the instrument Pre-Tune and Auto-Tune, or
RaPID (Response assisted PID) functions.
Control functions, alarm settings and other parameters are easily entered through the
front keypad. E

Technology (100 year life) protects against data loss during AC power
outages.
The input is user configurable to directly connect to either thermocouple, RTD, mVDC,
VDC or mADC inputs. The instrument can operate from either a 90-264 VAC, 50/60 HZ
power supply, or optional 24V AC/DC power supply.
Standard features include:
•Auto Tune
•Alarm Functions
•Auto/Manual Switching
•Process Retransmission
•Setpoint Retransmission
•Setpoint Ramp Rate
•Proportioning (Time or Current)/On-Off Control
•Single On-Off Control
•Single Time Proportioning Control
•Single Current Proportioning
Optional features include:
•Dual On-Off Control
•Dual Time Proportioning
•Dual Current Proportioning
•Dual Setpoint
•Remote Setpoint
•Digital Communications
•Alarm Outputs

1.2 Displays
Each instrument is provided with dual displays and status indicators as shown in Figure
1 -1. The upper display (RED) displays the value of the process variable. The lower
display (GREEN) displays the setpoint value.
1.3 Control
The instrument can be programmed for on-off, time proportioning, or current
proportioning control implementations depending on the model number. A second
control output is an available option. Proportional control implementations are provided
with fully programmable PID parameters.
1.4 Alarms
Alarm indication is standard on all instruments. Up to two alarm outputs are possible.
Alarm type may be set as Process Direct or Reverse (high or low), Deviation Direct or
Reverse (above or below setpoint), Deviation Band Type (closed or open within band),
or Loop Reverse or Direct. Alarm status is indicated by LED. An Alarm Inhibit is
provided to prevent, when activated, unwanted alarms during power-up.

1.5 Process Variable/Setpoint Value Re-Transmission Output
If the instrument is specified with this option, this output may be scaled over any
desired range and re-transmitted.

SECTION 2: INSTALLATION AND WIRING
2.1 Mounting
Electrical code requirements and safety standards should be observed and
installation performed by qualified personnel.
The electronic components of the instrument may be removed from the housing during
installation. To remove the components, grip the side edges of the front panel and pull
the instrument forward. During re-installation, the vertically mounted circuit boards
should be properly aligned in the housing.
Ensure that the instrument is correctly orientated. A stop will operate if an
attempt is made to insert the instrument incorrectly.
Recommended panel opening sizes are illustrated in Figure 2-1. After the opening is
properly cut, insert the instrument into the panel opening. Ensure that the panel gasket
is not distorted and that the instrument is positioned squarely against the panel. Slide
the mounting clamp into place on the instrument (see Figure 2-3) and push it forward
until it is firmly in contact with the rear face of the mounting panel.
Note: The mounting clamp tongues may engage either on the sides or the
top/bottom of the instrument housing, Therefore, when installing several
instruments side-by-side in one cut out, use the ratchets on the top/bottom faces.
