Section 1 Introduction 1B General Description 5B The Model 5620 Power Controller is an economical power controller for manually setting the voltage into resistive load (Fig. 1-1). It has provision for different idle and run power settings, and a timer to time the application of run power setting. This makes it ideal for laboratory or production applications requiring these capabilities.

Section 3 Installation 3B Installing the Model 5620 9B Installing the Model 5620 Power Controller is a quick and simple process. It requires: • Connecting the LOAD wires • Selecting the proper output conditioning • Connecting an external timer-start switch (optional) • Connecting the LINE wires (main power) 1. Using a Phillips screwdriver, remove the four Phillips screws on the front of the 5620 and lift the top cover off. 2.
Connecting the LOAD and Line Wires 1B 1. Pass the power source wire through the right lower strain relief clamp, and connect the wires to terminals labeled: LINE 1, LINE 2 and GROUND. 2. Tighten the screws on the strain relief clamps to secure the wires. Figure 3-2 Location of LINE, LOAD and GROUND terminals CAUTION! Line 2 must be neutral for all 120V installations. WARNING! Never operate the controller without proper GROUND wiring.
. Output Conditioning Selection 12B The 5620 Power has a jumper-selectable output conditioning feature, located on the lower circuit board, that changes the output voltage response time (Fig. 3-3). This feature protects the controller from excessive in-rush current when connected to resistive loads that have low resistance when cold. The three different response time settings are: Fast: For resistive loads where the cold-to-hot resistance is nearly constant. (.
Installing an Optional Remote Timer-Start Switch 13B 1. Remove the plug from the upper circuit board (Fig. 3-4). 2. Pass the Remote Timer-Start switch wire through the top strain relief clamp. 3. Fasten the two wires from a normally-open switch into the small compression lugs on the plug and tighten the screws. 4. Re-insert the plug onto the board. 5. Tighten the screws on the strain relief clamp to secure the wire. 6. Replace the top cover and the four Phillips screws.
Section 4 Operating Instructions 4B Introduction 10B Figure 4-1 displays the control panel for the 5620, and the following subsections describe how to use each feature. For safe and efficient operation of the Model 5620 Power Controller, heed all safety precautions discussed in Section 2. Figure 4-1 Model 5620 Control Panel How to Use the Standby-Operate Switch 14B The standby-operate switch disables the voltage output when in the standby position and enables the output when in the operate position.
Operating the RUN/IDLE/TIMER Features 15B The RUN/TIME ADJUST potentiometers provide a variety of operating modes. Using the RUN mode, the user can adjust the output from 0 to 100 percent of the input voltage. The TIME mode allows the user to preset a time of operation from 0 to 20 seconds. IDLE Adjustment 1. Place the STANDBY-OPERATE switch in the OPERATE position. 2. Place the RUN/IDLE/TIMER switch in the IDLE position. 3.
