ii ■ Watlow Power Series Table of Contents
1 Chapter One Overview Introduction The Power Series is a state-of-the-art microprocessor-based Silicon Controlled Rectifier (SCR) power controller intended for controlling industrial heaters. This product is based on one package with several configurations that include single phase, three phase, and single phase-multizone capabilities. Each package configuration has a specific current rating depending on the number of phases switched.
Single Phase This configuration can be purchased with any or all the features available on the Power Series. The only limitations are the features selected by the customer upon purchase. It has the highest current rating of all configurations since it is only switching one phase of the ac line. It is intended for resistive heaters, but can also be used on transformer connected loads in the phase angle firing mode.
2 Chapter Two Installation ∫ WARNING: To avoid potential electric shock and other hazards, all mounting and wiring for the Power Series must conform to the National Electric Code (NEC) and other locally applicable codes. NOTE: Ground must be wired with the same size wire as line and load connections to a ground of sufficient current carrying capacity. NOTE: Integral semiconductor fuses do not qualify as branch circuit protection.
Power Series Dimensions Power Series Front View 1 2 Add a 9-in. clearance dimension to help develop the chimney cooling effect. This should be on the top and bottom of the Power Series mounting. 337 mm (13.3 in.) 305 mm (12.0 in.) 7.1 mm (0.28 in.) 3 Power Series Top View Power Series Solid State Power Control Power Series Solid State Power Control 354 mm (14.0 in.) 421 mm (16.6 in.) 234.1 mm (9.2 in.) 356 mm (14.0 in.) 200 mm (7.9 in.) 178 mm (7.0 in.) 4 5 6 191 mm (7.5 in.) 191 mm (7.
Enclosure Guidelines The Power Series must be mounted in a suitable electrical enclosure. It must have adequate wire bending space and cooling. The maximum ambient temperature in the enclosure must not exceed 50°C (122°F) for name plate rating. For other output ratings and enclosure ambient temperatures, see output rating curves on pages 2.5 and 2.6.
ç CAUTION: You may want to use a large screwdriver to press in on the release tab while you are pushing on the controller to avoid potential injury to your hands. Removing the Power Series Controller 1. To release the Power Series controller from the mounting plate, press in on the release tab at the top of the mounting plate. 2. When the release tab is in, push up on the controller from the bottom to release it from the mounting plate. Beware of sharp edges on the heat sink when you push upward.
Power Series Output Rating Curves Fan Cooled All curves are at 100% on with 90°C rated load wire and line wire connected. Note that each chart is slightly different on the amperage scale. The safe operating region is from 1 amp up to the specific curve for the output amperage code selected. For example: F25 Single-Phase is rated up to 200 amps at 50°C; F30 Single-Phase is rated for 250 amps at 50°C. See page 2.6 for Natural Convection Cooled output rating curves.
Power Series Output Rating Curves Natural Convection All curves are at 100% on and with 90°C rated load wire and line wire connected. Note that each chart is slightly different on the amperage scale. The safe operating region is from 1 amp up to the specific curve for the output amperage code selected. For example: N25 Single Phase is rated up to 140 amps at 50°C; N30 Single Phase is rated for 165 amps at 50°C.
3 Chapter Three Wiring Wiring the Power Series Controller Wiring options depend on the model number. Check the terminal designation stickers on the right side of the controller and compare your model number to those shown here and with the model number breakdown in the Appendix (page A.10) of this manual. Chapter 3 illustrates how to wire the inputs and outputs for all options. Refer to Figure 3.1 for terminal torque guidelines.

5 Chapter Five Control Methods and Features Zero Cross Zero cross (also known as burst firing) provides even output power with the lowest level of noise generation (RFI). Zero cross is the preferred method for controlling a resistive load. The controller determines when the ac sine wave crosses the 0-volts point, then switches the load, minimizing RFI. Zero cross control is available for all Power Series configurations. Soft start and current limiting are not available with zero cross control.
Variable Time Base - Zero Cross Setup Page: In the variable time base control method, an optimal ratio of cycles on to cycles off is used to generate the desired power output. The number of cycles needed to completely generate a desired power level is variable in single cycle increments. Line voltage compensation algorithms are used to adjust the percentage power output while operating in this mode.
Soft Start Setup Page: Soft start is a variation of phase angle control executed on startup in which there is a gradual increase in power until the final selected power output is reached. If soft start is selected, the system will execute the soft start sequence each time a zone starts active control. This happens at power-on and on recovery from an alarm such as “Line Loss.” The soft start time is the time it takes to achieve 100 percent power after a zone restart.
Heater Bakeout If a system is shut down for long periods, some heaters can absorb moisture. With a standard power controller, turning the power full “on” when moisture is present, can cause the fuses or the heater to blow. However, with the Power Series you can now “bake out” the moisture in a wet heater before applying full power and destroying the heater. During heater bakeout, the Power Series slowly increases voltage to the heater while monitoring the output current.
Current Limiting Setup Page: The current limit uses the RMS current entered by the user. When a zone goes from 0.0% to a requested power greater than 0.0%, the software increments the output power by 0.1% increments per AC cycle until a current limit is detected. The software will continue to increment and decrement by 0.1% per AC cycle based on the current limit until the goal power is met. During normal operation (after the initial goal power is met), a detected current limit will cause decrements at 0.
Other Features Baseline Voltage and Voltage Compensation The baseline voltage is used by the controller to adjust the output so that the system power remains constant. This adjustment is called voltage compensation. The requested power is assumed to occur at the baseline voltage. If there are any deviations of the line voltage from the baseline voltage, the applied output power will be adjusted. For example, the starting line voltage of the system is 121 volts and the baseline voltage is set to 121 volts.
Alarms An alarm takes some action, usually notifying an operator, when a control parameter leaves a defined range. A user can configure how and when an alarm is triggered and whether it turns off automatically when the alarm condition is over. A description of the alarms and errors, why they occur, and how to troubleshoot them can be found on pages A.4 - A.7. Setup Page: • When the display reads [algo], press Î until[`alr] [`set] [`set] is displayed.
Communications Overview A Power Series controller can also be programmed and monitored by connecting it with a personal computer or programmable logic controller (PLC) via serial communications. To use this communications option, a Power Series must be equipped with an EIA/TIA 232/485 (P_ _ _ - _ _ _ _ - 1 _ _ _) communications board. To view or change controller settings with a personal computer, you need to run software that uses the Modbus™ RTU protocol to read or write to registers 5.
Retransmit Retransmitting Output Load Current or Load Power The retransmit feature allows an output to retransmit an analog signal that can serve as an input variable for another device such as a chart recorder to document system performance over time. Current outputs are hardware limited to 0 to 20mA, but may be scaled using the {rt|C_] and {rt|C–] prompts. Voltage outputs are hardware limited to 0 to 10V, but may be scaled using the {rt|U_] and {rt|U–] prompts.
