Step 3 Configure the Controller Step 3 Configure the Controller Overview of Configuration • Get to know the keys and how they function in different modes. • Review configuration and programming procedures in this guide. • Choose applications, functions, parameters and values (see Application Software Selection Table in this guide). • Review the operating instructions (in each application guide). • Get a complete idea of how the application works.
Step 3 Configure the Controller Software Structure The MINICHEF 2000 software uses three modes — Configuration Mode, Programming Mode and Operation Mode — and each mode contains up to three levels of functions, parameters and values. The Operation Mode is the default mode. MINICHEF 2000 [M``1] G A From the Menu Programming Mode, press the Home and Escape keys for two seconds to view the functions. FUNCTIONS Press the Up- or Down-arrow key to scroll through the functions.
Step 3 Configure the Controller MINICHEF 2000 [`idle] G A From the Operation Mode, press the Up- and Downarrow keys for two seconds to view the menus. H C B Edit Enter D F E Home Escape Press the Enter key to return to idle. MENUS Press the Up- or Down-arrow key to scroll through the menus. [M``1] [M``2] [M``3] B Enter D Home • • • Press the Edit key to view the parameters of the selected menu. Press the Home key for three seconds to return to idle.
Step 3 Configure the Controller Configuration Mode Quick Reference This is a list of all functions, parameters and values that are available through the Configuration Mode. (They are not all available for every application.) For a detailed explanation of parameters see the Appendix in this guide.
Step 3 Configure the Controller Function [tHErl] Thermal Parameter [tyPE`] [HYSt1] [HYSt2] [Pid`U] [tune1] [tune2] [ProP1] [rSEt1] [int`1] [rAtE1] [dEr`1] [CYcL1] [ProP2] [rSEt2] [int`2] [rAtE2] [dEr`2] [CYcL2] Temperature Control Type Hysteresis 1 Hysteresis 2 PID Units Auto-tuning, Channel 1 Auto-tuning, Channel 2 Proportional Band 1 Reset (integral) Gain 1 Integral Gain 1 Rate (derivative) Gain 1 Derivative Gain 1 PID Cycle Time 1 Proportional Band 2 Reset (integral) Gain 2 Integral Gain 2 Rate (deriv
Step 3 Configure the Controller On/off Temperature control On/off control switches the heat outputs either full on or full off, depending on the temperature sensor input, set point and hysteresis values. The hysteresis value creates a buffer zone that increases the time interval that the output is off or on. With hysteresis set to 1º the process value would stay closer to the set point, but the output would switch on and off more frequently.
Step 3 Configure the Controller Configuration Procedure Power up the control (24VÅ (ac) source required). 1. Access the Configuration Mode by pressing the Up-arrow and Down-arrow keys simultaneously for two seconds. [m``1] for automatic applications will appear on the display. [-----] will appear in manual applications. Then press the Home key and the Escape key simultaneously for two seconds. [etype] will appear on the display. It is the first in a list of functions. You are now in the Configuration Mode.
Step 3 Configure the Controller Note: When you are configuring your controller, always edit [Etype] and set the application number first (for example, [appl`] [```20]). The parameters that follow are based on it. In general, parameters that appear earlier on the list can influence the parameters and values that follow. 6. To change a value: press the Down-arrow key or the Up-arrow key. MINICHEF 2000 [```28] G H B Edit C Accept E F Back-Up 7.
Step 4 Program the Menus Step 4 Program the Menus Program Mode Quick Reference These are the functions, parameters and values that may be included in the Program Mode. Not all parameters will appear. Different parameters are relevant in different application numbers. For a detailed explanation, see the Appendix in this guide. Function [M`__] Menu Numbers XX Parameter Value/Description [Stpt1] Set point 1 Temperature of set point 1.
Step 4 Program the Menus [ALArn] Mid Menu Alarm [none], [Stir], [Add], [FLiP], [turn], [ALErt] [AtinE] Alarm Time Time before end of menu 0 - [tiNE1] (in seconds) [Hstpt] Hold Set Point Temperature at which the oven will operate during hold sequence Temp range low to temp range high. [Htine] Hold Time Run time of hold sequence. 0 = infinite. A setting >0 = hold time.
Step 4 Program the Menus Procedure to program the menus This procedure applies only to automatic applications. Menus for manual applications are explained in the application guides. 1. To enter the Program Mode, press the Up-arrow and Down-arrow keys simultaneously for approximately two seconds. [m``1] will appear on the display. This is menu number 1, the first in a list of sev- eral. You are now in the Program Mode.
Step 4 Program the Menus 5. To edit a value: with the parameter on the display, press the Edit key. The first value in a list of values will appear on the display. MINICHEF 2000 MINICHEF 2000 [650`f] stpt1] G G H H A B Edit Accept D E Exit Back-Up A B Edit Accept D E C Exit Back-Up C F F 6. To change a value: press the Down-arrow key to move down, press the Up-arrow key to increment up.
Step 5 Set Controller Security Step 5 Set Controller Security To Set Menu Security Lock Return to the Configuration Mode, to the [Setup] Function, and program the [Loc``] Parameter to adjust end-user access. When [loc``] is set to [``yes] the end user does not have access to the Menu Programming Mode and can only view parameter values. When [loc``] is set to [```no] the end user has access to the Menu Programming Mode and can change parameter values.
Step 6 Set the Real-time Clock Step 6 Set the Real-time Clock These instructions are optional and apply only to controllers that are purchased with the Real-time clock (time of day) option. (Part number example: F2 _ _ - _ _ _ _ - 1 _ _ _) To set the time of day 1. Press the Edit key and Home key simultaneously for approximately 3 seconds. You are now in the Real-time Clock Program Mode.
