1. Configuring Zone settings Configuring Zone settings Zone Speed settings The Speed parameter determines how fast the zone will respond to or anticipate changes in temperature While there are manual settings of Slow Medium or Fast the default setting is Auto This allows the zone to run the auto load sensor program described on page 11 during its first start and so determine which of the three manual settings best suits the load You can override this automatic selection by selecting one of three preferred speeds on a zone by zone basis as described here 1 Select the Setup page 2 Turn the wheel to select Spd on the required zone 3 Press the wheel twice to make the word AUTO on the top row blink then Turn it to change the zone speed from Auto to select the manual speed setting to either FAST MEDI Medium or SLOW then Press the wheel to select that speed 4 Ifyou need to set another function Standby or Boost temperature while on this page then Press the wheel again to select that function Otherwise if there is no other function to change then leave the wheel untouched for a short time and it will return to the Display page Setting the zone Boost and Standby Temperatures The Boost and Standby temperatures may be set on a zone by zone basis Both are set as temperatures above or below the set temperature as opposed to a specific temperature values These values can be set as described below 1 Select2.

13. er Works How the DMS Controller Works DMS controllers are designed to perform in closed and open loop configurations However we consider that the normal operating mode is closed loop Whenever the controller is set to start the system goes into a self calibration routine This is illustrated in the following diagram and explained below Personne a eg ee 5 ee A o 2 2 5 5 5 Load Test 3 oy 2 Soft rs Start Load Test Delay Prd Time e The zone controller slowly ramps up the heater power and simultaneously looks for a positive temperature change at the thermocouple input The controller verifies the actual rate of rise against a predetermined value Power is slowly increased until the correct rate of rise is achieved e The controller now increases the zone temperature at a constant rate of rise until the temperature reaches about 110 C 230 F e At 110 C the controller performs a Load Test on the zone heater to check its thermal characteristics The output power is reduced to zero for a test period and the temperature monitored for a response From all this information the controller has built mathematical model of the heater characteristics and so it can automatically select a Fast Medium or Slow response heating program that suits the tool This allows more efficient control of the zones e The controller continues to ramp up the temperature to the set point
