Selecting an EIA/TIA-232 to EIA/TIA-485 Converter 12 V GN Î ( 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 limit, 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.

Home Page Overview Operations Page Overview The Home Page is the default display of the Series SD limit controller. When the limit is powered up or you exit any other page, the Home Page appears. The parameters that appear in the Home Page are determined by the Display Look settings in the Setup Page (see Chapter 5). The process value is the default for the upper display and the High Limit Set Point is the default for the lower display.
Setup Page Overview [`SEt] [PAgE] Note: Hardware configuration and programming selections determine what parameters appear in the Setup Page. Setup Page The Setup Page contains parameters that define the basic limit functions. Go to the Setup Page for initial configuration or if your application requirements change. Be sure to program the Setup Page first! To go to the Setup Page, press both the Up ¿ and Down ¯ keys for three seconds from the Home Page.
Programming Page Overview [Prog] [PAgE] The Programming Page determines what parameters the user wants to appear in the Operations Page.

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.
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 limit to match the input device, which is normally a thermocouple, RTD or process transmitter.
Set Point Low Limit and High Limit High Range and Low Range The controller constrains the limit set point to a value between a low limit and a high limit. The high limit cannot be set higher than the sensor range high limit or lower than the sensor range low limit. The low limit cannot be set lower than the sensor range low limit or higher than the sensor range high limit. Set the limit set point range with Set Point Low [SP;Lo] and Set Point High [SP;hi] (Setup Page).
Alarm Set Points The alarm state begins when the temperature reaches the Alarm High Set Point Alarm High Set Point Alarm Hysteresis Temperature The alarm high set point defines the process value or temperature that will trigger a high side alarm. It must be higher than the alarm low set point and lower than the high limit of the sensor range. The alarm low set point defines the temperature that will trigger a low side alarm.
Overview A Series SD controller can also be programmed and monitored by connecting it with a personal computer or programmable logic controller (PLC) via serial communications. To do this it must be equipped with an EIA/TIA 485 (SD_ _ - _ _ U_ - _ _ _ _) communications option for Output 2. Your PC or PLC must have available an EIA/TIA-485 interface or use an EIA/TIA-232 to EIA/TIA-485 converter. See “Selecting an EIA/TIA-232 to EIA/TIA-485 converter” in Chapter 2.
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.
Indication Probable Cause(s) Corrective Action Getting limit message [L1;hi], [L2;hi], [L3;hi], [L1;Lo], [L2;Lo] or [L3;Lo]. The process value is beyond a limit set point. Determine when limit messages will display and the proper response to a limit message. Getting alarm message [A2hi] or [A3hi], [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. Limit or alarm is occurring when it should not.
Error Messages Indication Probable Cause(s) Corrective Action [Er;In] Input error The sensor may be improperly wired. Sensor wiring may be reversed, shorted or open. The input may be set to the wrong sensor or the controller may not be calibrated. Calibration may have been corrupted. Check sensor connections. Check sensor connections and sensor wiring. Change Sensor Type [`Sen] (Setup Page) to match the sensor hardware. Restore factory calibration.
