Introduction Welcome to the Watlow Series 935B! General Description The Series 935B is a temperature controller with countdown timer for industrial, commercial, or scientific applications. It offers 1/32 DIN panel-mounting, digital indication, single temperature sensor input from a thermocouple or RTD, and dual control outputs. Both outputs are fully DIN-a-mite® compatible, and may operate in combinations of heat or cool, and alarm or timer.

Begin Controlling To Begin Controlling: 1. Apply power to the system. A properly-wired Series 935B will begin controlling the thermal system as soon as you apply power to it. 2. Look at the Series 935B’s display. It is reading actual temperature, set point temperature, or time. • To change set point, go to p. 9. • The Series 935B will auto-tune when you tell it to, go to p. 34. • If you see an error, go to p. 10.
Change Set Point To Change the Set Point: Your Series 935B displays the actual process temperature when it comes from the factory. You can change it to normally display the set point or time. Go to p. 18, see [dISP]. 1. Press and hold ß. 2. Press one of the arrow keys to alter the set point either upward or downward. 3. Release ß to complete the change.
Respond to a simple error If You See An Error Code: 1. Be aware that most errors are input (sensor) related. 2. Read the table below and follow its recommendations.

Learn Easy Software Map Software Organization • The Series 935B has three primary menus in addition to a normal display. • The software reverts to the normal display after 60 ± 5 sec. with no key action. Table 3 - Software Organization Display Actual Temperature, Set Point, or Time Remaining • To access the Operations Menu, press the . and , keys simultaneously for three seconds. Operations, p. 12 PID, p. 14 Configuration, p.
Learn the Operations Menu The Series 935B Operations Menu is the first menu you encounter when you press the . and , keys simultaneously for three seconds. The Operations Menu provides a location to initiate the following actions or complete the following tasks: • Auto-tune [`Aut]: Start or stop the auto-tuning process. Auto-tuning selects a set of viable proportional, integral, and derivative values for heat and/or cool output.
Table 4 - Operations Menu Overview To enter the Operations Menu, press the . and , keys simultaneously for three seconds. Auto-tune - Start the auto-tune action to automatically select a set of viable PID values; [tunE] will flash during auto-tuning. [`Aut] [``no] [`YES] NO YES Alarm Low - Select a low alarm point, adjustable between Off, Range Low and Alarm High. [`ALO] [`AhI] Alarm High Alarm High - Select a high alarm point, adjustable between Alarm Low and Range High, or OFF.
Learn the PID Menu Choosing a PID Setting Strategy You may rely solely on the Auto-tune [`Aut] function (p. 34) and factory defaults to determine PID values for your system, or you may use auto-tuning and additional manual adjustments. You must select dead band [``db] and calibration offset [`CAL] values manually. The Series 935B PID Menu is the first sub-menu you encounter after moving to the Operations Menu.
Setting PID Menu Values • Proportional Band, Heat and Cool [Pb`h] and [Pb`c]: Select a value (degrees) to set up band on either side (±) of the Primary Set Point in which the heat and/or cool proportioning function(s) will be active. For on/off control, set [Pb`h] or [Pb`c] = 0. Range: 0 to 999°F/555°C, or 0.0 to 999.0°F/555.0°C Default: 25°F/17°C, or 25.0°F/17.0°C • Hysteresis, Heat and Cool [hYSh] and [hYSc]: For use with on/off control only.
