1. 5 Rate Derivative Adjustment Increasel cl JI d to 1 00 minute Then raise the set point by 11 to 17 C or 20 to 30 F Observe the system s approach to the set point If the load temperature overshoots the set point in crease _ f __ dE to 2 00 minutes Raise the set point by 11 to 17 C or 20 to 30 F and watch the approach to the new set point If you increase _ el ___ dE too much the approach to the set point is very sluggish Repeat as necessary until the system rises to the new set point without overshooting or approaching the set point too slowly 6 Calibration Offset Adjustment You may want your system to control to a temperature other than the value coming from the input sensor If so measure the difference between that temperature perhaps at another point in the system and the process value showing in the upper display Then enter the calibration offset value you want Calibration offset adds or sub tracts degrees from the value of the input signal 5 2 E Tuning and Operating Watlow Series 93 NOTE A process input does not have sensor break protection or bump less transfer Outputs selected as reverse acting will be full on if a sensor break occurs Manual and Automatic Operation To change from auto to manual operation press the Infinity key twice Manual operation provides open loop control of the outputs from a range of 100 full cooling to 100 full he
2. Ai Ee Mounting Collar External Gasket Teeth 3 While pressing the front of the case firmly against the panel slide the mounting collar over the back of the controller The tabs on the collar must line up with the mounting ridges on the case for secure installation See Figure 2a Slide the collar firmly against the back of the panel getting it as tight as possible To ensure a tight seal use your thumb to lock the tabs into place while press ing the case from side to side Don t be afraid to apply enough pressure to install the controller The tabs on each side of the collar have teeth which latch into the ridges See Figure 2b Each tooth is staggered at a different height so only one of the tabs on each side are ever locked into the ridges at any time Confirm that the tabs on one side of the collar correspond with those on the opposite side Make sure the two corresponding tabs are the only ones locked in the ridges at the same time If the corresponding tabs are not supporting the case at the same time and the space between the panel and the case bezel is greater than 019 inch you will will not have a IP65 NEMA 4X seal This applies to units with models designated 93B However all units should be mounted in this fashion to guarantee integrity of the mounting system Ba IP65 NEMA 4X Seal Example Make sure that the two corresponding tabs are locked in the ridges at the same time 4 Insert the control

4. To start autotuning 1 Press the Advance key until the prompt appears in the data display 2 Select a thermal response value using the QUp arrow QDown arrow keys 1 for a slow response 2 for an average response and 3 for a system that responds quickly A thermal response value of 2 satisfactorily tunes most thermal systems 3 Press the Advance key While the controller is in the tuning mode the lower display alternately displays the normal information and the prompt BUEL at one second intervals Watlow Series 93 Tuning and Operating 5 1 gt VH DA gt E Les KZ a gt fas gt VC NOTE Tune heating outputs at a set point above ambient temperature Tune cooling outputs at a set point below ambient temperature 4 When tuning is complete the displays return to their previous state and reverts to 0 The Series 93 installs appropriate PID tuning parameters and saves them in the non volatile memory If a mechanical relay or contac tor is switching power to the load a longer cycle time may be desirable to minimize wear on the mechanical components Typical life of a me chanical relay is 100 000 cycles To abort autotuning either reset the parameter to 0 press the Infinity key twice or cycle power off and on In all cases aborting autotune restores all values to those previous to autotuning Manual Tuning For optimum controller performance tune the Series 93 to yo
