Page 5: Section 1 Overview
Section 1 Overview This instrument records process trend lines, one or two pens, on a 10 inch circular chart. As an option, up to two alarm points are provided for each of the two pens. This recorder will accept J, K, T, R, and S Thermocouples and RTD inputs, as well as typical Millivolt, Milliamp (4-20mA) and Volt inputs, (up to 5 volts). -
Page 6: Section 2 - Installation & Wiring
Section 2 Installation and Wiring Read these instructions completely and carefully before proceeding with the installation and operation of this recorder. Electrical code requirements and safety standards should be observed. Installation should be performed by qualified person- nel only. Caution: The standard recorder will accept a power input over the range of 90-264 VAC. There is a special low power voltage option that is available. - Page 7 SURFACE MOUNTING: 1. Loosen the mounting brackets attached to the recorder and flip their position so the ears are flush with the back of he recorder. Fasten the recorder to the surface using the appropriate fasteners (#10 screws or nuts and bolts) depending on the surface material.

Page 8: Preparation For Wiring
2.3 PREPARATION FOR WIRING Electrical noise interference is a phenomenon typical of industrial environments. Use the following guidelines which are generally used to minimize the effect of electrical noise on instrumentation in general. 2.3.1 WIRING GUIDELINES Listed below are some of the common sources of electrical noise in the industrial environment: •... - Page 9 FIGURE 2-2 Inductive A.C. Load FIGURE 2-3 Inductive A.C. Load 2.3.1 SENSOR PLACEMENT If the input probe will be subjected to corrosive or abrasive conditions, it should be protected by the appropriate thermowell. The probe should be positioned to reflect the true process temperature: In liquid media - the most agitated area In air - the best circulated area For thermocouple sensors, the lead resistance should not exceed 300 ohms.

Page 11: Wiring Connections
2.4 WIRING CONNECTIONS WARNING: Avoid electrical shock. AC power wiring must not be connected at the source distribution panel until all wiring connections are completed. All wiring connections are typically made to the instrument at the time of installation. All connections are made behind the access door on the recorder right side. - Page 12 2.4.1 ELECTRICAL CONDUIT OPENINGS The instrument case has 3 conduit openings, all on the right hand side of the case. To minimize the effect of electrical noise, the following wire groups should be routed through the conduit openings as shown below. Top Conduit Opening - Power Input - TB1 Middle Conduit Opening - Input Signal Wiring &...
- Page 13 2.4.4 RELAY OUTPUT WIRING Relay outputs, up to 2 for each pen, are provided as an option on this instrument with a separate circuit board that is mounted in the lower right hand corner of the instrument, near the lower electrical conduit hole. Wire up each relay as shown in Figure 2-7.
- Page 14 2.4.6 TRANSMITTER POWER SUPPLY WIRING Connections are made as shown using TB10, terminal 2 as positive (+) and terminal 1 as negative (-). See Figure 2-9A for one transmitter and Figure 2-9B for two transmitters (40mA DC maximum). FIGURE 2-9A TB2/TB3 TB10 Shield...

Page 15: Section 3 Normal Operation
Section 3 Normal Operation Assuming that the MODE switch (discussed later) is in the RUN position, on power up, the recorder will display the software revision, in the format rX.XX, while the pens move to the home position (toward the center of the chart). Then the instrument will display the model number. -
Page 16: Control Output Settings
3.2 CONTROL OUTPUT SETTINGS 3.2.1 SINGLE OUTPUT When Single Output On/Off control is configured as CH (Control Heat), the relay will turn OFF when the process value is greater than the setpoint by one-half the hysteresis value and turn ON when the process value is less than the setpoint by one-half the hysteresis value. -
Page 17: Alarm Settings
3.3 ALARM SETTINGS There are two possible alarm set point values for each of the two possible inputs/pens. They will be displayed only if the alarm options are present and configured. The types of alarms and the ability to make alarm set point changes, is defined during configuration. -
Page 18: Hardware Selections - Input Jumper Positions
4.1 HARDWARE SELECTIONS - INPUT JUMPER POSITIONS Hardware jumpers JU1 and JU2 are used to select the input type for Pen 1 and Pen 2 respectively. The jumper positions are shown on the main wiring label on the recorder as well as on the Short Form Programming Card. See below: JU1 and JU2 Positions - JU1 is located between wiring terminals TB2 and TB3 on the edge of the main board. - Page 19 These parameters apply to each pen, assuming pen 2 is present, and are configured in each respective section.

Page 21: Test Mode
4.3 TEST MODE - TEST To enter the Test mode, press SCROLL until tESt shows on the display. Press DOWN to enter the Test mode. Press SCROLL to display the various tests (diSP and Chrt). Press DOWN to enter a test section. 4.3.1 Display, Keypad, and Relay Test - diSP Once you enter the Display/Keypad/Relay test by depressing DOWN, the display should first show all 8s with decimal points and all status LEDs lit for about 5 seconds. -
Page 22: Section 5 - Recorder Calibration Mode
Section 5 Recorder Calibration Mode - CAL As covered in Section 4, the "calibration seal" may need to be removed to access the MODE switch to gain access to the calibration section. The MODE switch must be positioned to the PROG/TEST/CAL position. CAUTION: DO NOT ATTEMPT ANY CALIBRATIONS WITHOUT THE PROPER TEST EQUIPMENT THAT MEETS OR EXCEEDS THE SPECIFICATIONS LISTED. -
Page 23: Chart/Pen Calibration
3=Milliamp for all milliamp ranges. 4=RTD for all RTD ranges. 5=Cold Junction Compensation for all T/C ranges. After selecting the proper range code, depress the SCROLL key and rEF should be displayed. With rEF displayed, depress the SCROLL key to display the value for the source to be connected. Connect the input source set for this value to the selected input terminals. -
Page 24: Section 6 Model Number Changes
PEN ARC MECHANICAL ADJUSTMENTS Important Note: Pen arc adjustments have been done at the factory and should not need to be done in the field, unless the pen arm adjustments (mechanical) have been compromised. (This can happen if the pens are forcibly moved.) Adjustments can be made at the bottom or top of span. - Page 25 Appendix A - Model Number Matrix SUFFIX FIRST PEN OPTION Blank None Recorder Only Alarms And Communications Controller Connectivity Option High/Low Limit* (Allows for later field installation of both options) SECOND PEN OPTION VOLTAGE None Standard (90-264 VAC) Recorder Only Low Voltage** Controller Standard Voltage Operation...
