Selecting an EIA/TIA-232 to EIA/TIA-485 Converter 12 V GN ( GND dc) TD D ( TD B) (A ) When choosing an EIA/TIA 232 to 485 converter, look for one with the following features: Two-wire capability EIA/TIA-485 can be implemented as a two-wire system or a four-wire system. Most Watlow controllers, including the Series SD, use two-wire communications when working with EIA/TIA-485. The converter selected must have a two-wire mode. Some converters can only be used in a four-wire mode.
Ethernet Gateway The EM00-GATE-0000 is a bridge that allows up to 32 Watlow controllers to be directly connected to an Ethernet network. The gateway provides a bridge for Modbus messages between the Ethernet bus and EIA-485 or EIA-232 links. The Gateway supports full product configuration monitoring and configuration of runtime parameters via MODBUS TCP over TCP/IP using a software package such as Watlow’s WATVIEW™. The Series SD can be configured using WATVIEW with or without the EM Gateway.

Saving and Restoring User Settings Recording setup and operations parameter settings for future reference is very important. If you unintentionally change these, you will need to program the correct settings back into the controller to return the equipment to operational condition. After you program the controller and verify proper operation, use [USr;S] to save the settings into a special section of memory.
Press the Advance Key ‰ once to go to the first selection in the page. The parameter choices will appear in the top display and the selection number will appear in the bottom display. Use the Up ¿ or the Down ¯ key to change the selected parameter in the top display. If you do not want a parameter to appear for that location, select [nonE].
Calibration Offset Sensor Selection Calibration offset allows a device to compensate for an inaccurate sensor, lead resistance or other factors that affect the input value. A positive offset increases the input value, and a negative offset decreases the input value. The input offset value can be viewed or changed with Calibration Offset [`CAL] (Operations parameters). You need to configure the controller to match the input device, which is normally a thermocouple, RTD or process transmitter.
High Scale and Low Scale When an analog input is selected as process voltage or process current input, you must choose the value of voltage or current to be the low and high ends. For example, when using a 4 to 20 mA input, the scale low value would be 4.00 mA and the scale high value would be 20.00 mA. Commonly used scale ranges are: 0 to 20 mA, 4 to 20 mA, 0 to 5V, 1 to 5V and 0 to 10V. The Series SD allows you to create a scale range for special applications other than the standard ones listed above.
On-Off Control On-off control switches the output either full on or full off, depending on the input, set point and hysteresis values. The hysteresis value indicates the amount the process value must deviate from the set point to turn on the output. Increasing the value decreases the number of times the output will cycle. Decreasing hysteresis improves controllability.
The droop caused by proportional control can be corrected by adding integral (reset) control. When the system settles down, the integral value is tuned to bring the temperature or process value closer to the set point. Integral determines the speed of the correction, but this may increase the overshoot at startup or when the set point is changed. Too much integral action will make the system unstable. Integral is cleared when the process value is outside of the proportional band.
Curve 1 is for oil cooled extruders and curve 2 is for water cooled extruders. Change the linearity for each output with Output Non-linear Function 1, 2 or 3 ([nLf1], [nlf2] or [nlf3]) in the Setup Page. 100 Actual Output Power would result in an actual output power level of 50%. But if the PID calculated power output is 100%, then the power level will be 70%. Power scaling establishes the maximum power output and the minimum power output. The output power is then linearly scaled within that range.
Temperature Set Point Temperature reaches Set Point quickly Time Set Point Temperature put is distributed in groupings of three ac line cycles. For each group of three ac line cycles, the controller decides whether the power should be on or off. There is no fixed cycle time since the decision is made for each group of cycles.
Alarm Hysteresis Alarm Silencing An alarm state is triggered when the process value reaches the alarm high or alarm low set point. Alarm hysteresis defines how far the process must return into the normal operating range before the alarm can be cleared. Alarm hysteresis is a zone inside each alarm set point. This zone is defined by adding the hysteresis value to the alarm low set point or subtracting the hysteresis value from the alarm high set point.
485 option directly supports communication with up to 32 devices on a network or up to 247 devices using a 485 repeater. Basic communications settings must first be configured on the controller in the Setup Page. Match the Baud Rate [baUd] to that of the computer and select a unique Address [Addr] for each Series SD. 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 in the controller.
6. Test the communications. Once communications is configured, test the link to the controller for verification that everything is wired and configured properly. Check the wiring and configurations if things aren’t working. One misplaced wire or one incorrect setting will keep communications from working.
Troubleshooting Indication Probable Cause(s) Corrective Action No power. Controller appears dead. No display indication in either window. Power to unit may be off. Fuse may be blown. Breaker may be tripped. Safety interlock door switch, etc. may be activated. Separate system limit control may be latched. Wiring may be open. Input power may be incorrect. Check switches, fuses, breakers, interlocks, limit devices, connectors, etc. for energized condition and proper connection.
Troubleshooting Indication Probable Cause(s) Corrective Action Getting alarm message [A1hi], [A2hi], [A3hi], [A1Lo], [A2Lo] or [A3Lo]. The process value is beyond an alarm set point. Determine when alarms messages will display and the proper response to an alarm message. Alarm is occurring when it should not. Alarm settings are incorrect. Adjust the alarm settings to be correct for the application. Input may be in an error condition. See error messages. Alarm may be latched.
Troubleshooting Indication Probable Cause(s) Corrective Action Profile will not start. or resume. Lower display flashes between static set point value and File Number / Step Number. For example, if File 1, Step 1 is not valid, the display will flash 1.1 Profile step has target set point or Wait-for Process values that are outside of [SP;lo] or [SP;hi] values. Jump Loop step is trying to jump to itself. Keep target set point or Wait-for Process values inside set point limits or adjust set point limits.
