Product Description 1.1

1.1.1 GENERAL

The unit is a circular chart recording instrument capable of measuring, recording, and
controlling up to two process variables from a variety of inputs. Applications include
temperature (degrees F and C), pressure, relative humidity, pH level, electrical measurement,
flow and others.

Instrument capabilities such as recording, controlling functions, alarm settings, and other
parameters are selected from the order matrix and are factory implemented.

The process input for each pen is configured, at the factory, per order matrix model selection
and directly connects to either thermocouple, RTD, mVDC, VDC, or mADC inputs. Most
changes to input type are easily accomplished in the field. However, an input change from
thermocouple to RTD on units with Recorder PWA's at revisions before Rev D should be done
only after consulting with factory. Inputs are factory calibrated and will require re-calibration if
changed in any way. Thermocouple cold junction compensation is performed automatically by
the instrument.

The instrument can operate with either 115VAC or 230VAC line voltage at 50 or 60Hz. The
voltage and frequency are selected when ordering. The 230VAC line voltage option includes
soldered jumpers to allow the electronics to be configured to 115VAC line voltage when
necessary. The chart drive is not switchable, and must be changed whenever the line
voltage or frequency is changed.

PAGE 5

The instrument is housed in a durable enclosure suitable for panel or surface mounting.

1.1.2 RECORDING

The unit incorporates a 10 inch circular chart. One box of standard charts is provided with
each instrument. Charts are available in a wide selection of zero based, non-zero based,
reverse, and dual scale ranges. The instrument can be provided with one or two pens. Pen
1 is red and Pen 2 is green. Pens are of the disposable fiber-tip type. Changes in pens, as
well as charts, are quickly and easily accomplished.

Displays & Status Indicators

Setpoint is selected/observed using a 3 or 4 - digit pushbutton thumbwheel potentiometer.
Two LED indicators are provided :

INDICATOR COLOR DESCRIPTION
OUT1 Red Output 1 status

Installation & Wiring 2.1

At shipment from the factory the instrument has been configured to accept input(s) as
specified. AC power input is as specified in the model number; 115VAC or 230VAC. Verify
the AC power input provided with the instrument prior to proceeding with installation.

Read these instructions carefully before proceeding with installation and operation. Electrical
code requirements and safety standards should be observed. Installation should be per­formed by qualified personnel.

Installation of the Instrument includes:
* Unpacking
* Location
* Mounting
* Preparation for Wiring
* Wiring Connections

Unpacking 2.2

Remove the instrument from the carton and inspect it for any damage due to shipment. If any
damage is noticed due to transit, report and file a claim with the carrier. Write the model
number and serial number of the instrument on the front cover of this Operation Manual for
future reference when corresponding with the factory.

Location 2.3

Locate the instrument away from excessive moisture, oil, dust, and vibration. Do not subject
the instrument to operating temperatures outside of 0 to 55° C. (0 to 131°F)

Mounting 2.4

Figure 2-1 shows installation view and physical dimensions for the panel mounted instrument.
The panel that the instrument will be mounted in must provide rigid support for the approxi-

mately 20 pound Instrument. Adjacent Recorders or Recording Controllers may be mounted
within a minimum of 2 inches horizontally and 3 inches vertically, providing that proper panel
support is supplied.

PANEL MOUNTING HARDWARE REQUIRED: ( Not provided with instrument)

(4) 9/32" x 2" bolts w/nuts
(4) appropriate lockwashers

The location of the instrument is important and should be located in an area void of excessive
moisture, vibration, oil, and dust. The instrument should also be located in an ambient
temperature of 0 to 55° C (32 to 131° F).

For panel mounting, cut the panel hole to the dimensions shown in Figure 2-1 (page 9). If the
rear of the panel is accessible for wiring after installation, mount the instrument in the panel by
opening the hinged cover and fastening the instrument to the panel through the mounting
holes located in the case flange. If the rear of the panel is not accessible, the instrument must
be wired first. In this case, see wiring instructions.

For surface mounting, install the brackets ordered separately to the sides of the instrument
case and mount to the surface.

Preparation for Wiring 2.5

This section is divided into two parts: Wiring Guidelines, and Sensor Placement. Please
review this completely before proceeding with wiring of instrument.

The wiring guidelines contained in the following paragraphs must be followed to
ensure the best possible performance of the instrument. Please review this section
carefully before proceeding.

2.5.1 WIRING GUIDELINES

2.5.1.1 AC POWER WIRING

Clean AC power is required to ensure a proper installation. To be classified "clean" the
following must be met:

Earth Ground
Earth ground must be attached to the instrument's chassis. To verify that it is earth ground
being attached, make a resistance check from instrument chassis to the nearest metal water
pipe or proven earth ground. This reading should not exceed 1000 ohms.

2.5.1.2 WIRE ISOLATION

3 conduit openings, EC1, EC2, and EC3 are provided so wiring can be divided into separated
catagories.

* Analog input or output (i.e. thermocouple, RTD, VDC, mVDC or mADC)
* SPDT Relay or SSR driver outputs
* AC power

The only wires that should be run together are those of the same category. Each of these
must be isolated from each other .

2.5.2 SENSOR PLACEMENT (Thermocouple or RTD)

Thermocouple lead resistance should not exceed 300 ohms.
If this is exceeded, instrument accuracy could be affected.

Two wire RTD's should be used only for lead lengths less than 10 feet.
If the temperature probe is to be subjected to corrosive or abrasive conditions, it should be

protected by the appropriate thermowell. The probe should be positioned to reflect true
process temperature:

In liquid media - the most agitated area.
In air - the best circulated area.

Wiring Connections 2.6

All wiring connections are typically made to the instrument with it installed. Terminal connec­tions should be made via terminal blocks with captive wire clamps, two 12 gauge wires
maximum.

Use the wiring connections, Figure 2-3 (page 12), for planning all wiring installation. The
layout in Figure 2-3 shows the general location and orientation of all terminal blocks. Termi­nal blocks are designated TB1 thru TB6. Figure 2-3 shows details for the various possible
input connections. Paragraph 2.6.2 provides descriptive detail for AC power connections.
Paragraph 2.6.3 details all input connections, and paragraph 2.6.4 provides wiring connection
details for all outputs.

2.6.1 ELECTRICAL CONDUIT OPENINGS

Figure 2-1 shows the location of all electrical conduit openings that are provided on the
instruments. These openings are labeled EC1 thru EC3. It is recommended that wiring enter
the instrument through the conduit openings provided as follows:
EC1 - AC power
EC2 - Analog input and mAdc outputs
EC3 - SPDT relay or SSR driver outputs

Following these recommendations will help ensure proper operation .
Unused conduit openings should be sealed if exposed to the environment.

2.6.2 AC POWER WIRING CONNECTIONS

Avoid electrical shock. AC power wiring must not be connected at the source
distribution panel until all wiring connection procedures are completed.

Consult the model code and the wiring label for the appropriate line voltage for the unit.

Instruments specified with 230VAC power input, as specified in model number, are
provided with a soldered jumper which allows configuration back to 115VAC. Verify
soldered jumper configuration before proceeding with AC power wiring (see Fig.
4-4). Also ensure correct AC chart drive motor is installed (line voltage is stamped
on motor.

PAGE 11

CONNECT AC WIRING AS FOLLOWS:

1. Run AC power cable through the EC1 conduit opening as shown in Figure 2-1 (page 9).

2. Connect AC hot and neutral to terminals 1 and 2 respectively of TB1 as shown in
Figure 2-2 (below).

3. Connect Earth Ground to the instrument ground screw as shown in Figure 2-3 (page 12).

4. If Event Pen option is present, connect the 115VAC power through the EC1 conduit
opening as shown in Figure 2-1 (page 9) and as labeled in Figure 2-3A (page 12).

regardless of which line voltage supply used for instrument supply, event pen
operating voltage is 115 VAC only.

The event pen marks the circular chart on the outside edge of the paper. The pen
movement is short but a distinct difference can be seen between the On and Off cycles of
the pen. Typical event pen usage is for indication of an alarm condition.
