Page 9: Introduction
An increase in current normally indicates a rising liquid level. An outage (reverse) reading current output option is available. A typical installation of the 8200 COT consists of directly mounting it onto a 2500 ATG gaugehead. It may also be mounted onto a gaugehead of other manufacturers. - Page 10 Introduction Installation and Operations Manual...

Page 11: Installation
Operations Manual Mounting on Varec Gaugeheads The 8200 COT is suitable for installation on 2500 ATG gaugeheads or on the gaugeheads of other manufacturers. This procedure provides instructions to mount the transmitter on a 2500 ATG gaugehead, as shown in Figure 2-1 on page 4. - Page 12 Figure 2-1: Typical Tank Installation Each 8200 COT requires two wires for analog signals. DC versions are loop powered while AC versions require an additional three wires for power. Warning! Whenever the back cover of the gaugehead is removed, stand to one side as the last bolt is removed.
- Page 13 Loosen the slotted drive coupling set screw using an Allen wrench. Set the transmitter to the actual liquid level in the tank by rotating the field adjust knob located at the end of the shaft. Once the level has been set, re-tighten the set screw. Proceed with field wiring. Varec, Inc.

Page 14: Mounting On Alternate Gaugeheads
Each transmitter has a two-conductor signal cable back to the control room. If AC power is required, an additional three-conductor cable is wired to the 8200 COT, either 110 VAC or 220 – 240 VAC. Follow national and local codes for wiring of power and signal cables. -
Page 15: With Ac Wiring
Connect the (-) lead of the user power to L4. Note No load resistor is normally necessary if the receiving device is an analog current sensing device operating within the jumpered range. Refer to the instructions for the device in use. Varec, Inc. -
Page 16: Jumper Settings
Two sets of jumpers provide the user the selection of the current output ranges and input voltage ranges. If the optional Varec on-board 110/220 power supply is used, the VAC selection must be made. The two AC jumpers must both be set to the applied AC voltage, 110 VAC or 220 VAC. - Page 17 Check that the 4-20/10-50 jumper is set for the current output range of the instrument load loop that is to be used.

Current Output Transmitter Junction Boxes and Limit Switches The 8200 COT is shown with optional junction box in Figure 2-6. See Figures 2-8 and Figure 2-9 on page 13, and the accompanying tables for details regarding junction box connections. The 8200 COT offers two or four limit switches as options. The wiring is pre-wired Normally Closed (N.C.). - Page 20 Installation Refer to Table 2-1 on page 12 for more information on limit switch connections.

Page 22: 2.10 Initial Calibration
Note If the transmitter uses an internal power supply, the value of the DC POWER SUPPLY VOLTAGE entered into the equation is 30 VDC. Varec recommends that 22 gauge or larger size wiring be used. (The larger the gauge number the smaller the wire diameter.) Typical telephone field wiring is 21 gauge or larger. Mechanical field conditions affect the wire choice as well as cost. -

Page 25: Configuration
Calibration The 8200 COT(s) are calibrated at the factory for full-scale operation. The scale of the transmitter, however, can be set to any range between 45% and 100%. See Figure 3-1 on page 18 for the calibration wiring and setup. Note that a power supply is needed for the calibration procedure. - Page 26 Configuration On-Board Power Supply Green White Zero VR2 “ “ “ “ “ “ “ “ B lack Span VR1 “ Current output board Multimeter Off-Board Power Supply External power supply 1 5 - 4 8 V D C “ “ “...
