6 Theory of Operation The set-up of the individual and global loop parameters is explained in the Owner Set-up and Setpoints Tab sections of this manual. This Theory of Operation overview is intended to give a quick summary of how it all works together. Each loop of the system may be enabled (active) or disabled (inactive). A disabled loop will have no output and will not map into the common alarm. It will display Loop # and Loop Disabled text in the middle of the screen. Alarms for disabled loops will not be monitored or displayed on the screen. Each loop of the system may use unique individual control parameters or the control parameters may be alike. The Global Settings function facilitates this action. The GFEP and Load current are automatically and continuously being calculated. The horizontal yellow bar indicates the average output current for that circuit. The GFEP current value is not displayed on the screen but its value is compared to the GFEP setpoint. A GFEP alarm condition will occur when the GFEP current value exceeds the GFEP setpoint value. If a ground fault is detected during normal operation and Trip checkbox on the Setup screen is checked, the output of the defective loop is set to 0% and that loop goes into an alarm condition. If Trip checkbox is not checked, the operation of that loop continues and that loop goes into alarm condition. During extended periods of time where the output of all loops are off, such as during warmer seasons, the Auto Cycle feature may be engaged. This feature initiates ground fault and current testing. Each output is tested for one minute within the desired Auto Cycle Interval. The Auto Cycle feature may be disabled by setting the Auto Cycle Interval time to 0 Hours. To limit inrush current on the overall system, a proprietary Soft Start algorithm is applied during sys- tem start-up. This will ONLY occur while the operation mode is set to AUTO. The Soft Start program will increment output % by 1% every 1 second until the desired temperature is reached or the output % achieves 100%. After the Soft Start program completes its cycle, the Control Mode of the system will either be PID or ON/OFF Control Mode, depending what was selected by the user. The Soft Start Program will not function if the control mode is set to Manual. 3

7 Before Powering Up Chromalox takes great pride in knowing that we have provided to you a product of premium quality and workman- ship. We have taken every precaution to ensure that your equipment arrives safe and secure. However, vibration and temperature changes during shipping can cause some components to become loose. Additionally, throughout the life span of this product, other environmental and application conditions may have affected the mechanical and electrical continuity of several internal components. Therefore, for your safety and overall product performance, please take the time to familiarize yourself with the MAINTENANCE, OPERATION, AND INSTALLATION INSTRUCTIONS technical manual that was shipped with your panel. Since it is not uncommon for electrical wiring and mechanical connections to become slightly loosened during shipment, we ask that you pay particular attention to section 4-5.3 Wiring and Connections: 4-5.3 WIRING AND CONNECTIONS. Check wiring and connections as follows: a. Inspect wiring for wear, fraying, chipping, nicks, and evidence of over- heating. Repair minor defects with a good grade of electrical tape, or replace if needed. b. Inspect for loose electrical and mechanical connections. Tighten or replace defective crimp-style lugs. Re-solder loose solder connections. Tighten or replace all loose or missing hardware. 4

8 Main Menu Screen The ITAS/ITLS Touch Screen Computer is extremely user friendly and quite intuitive. Navigation to any other screens or any 6-Loop grouping of loops is accomplished by selecting the gray labeled buttons along the bottom of the screen or in the upper right or left hand corners. The main menu screen displays alarm status, loop number, loop name, process and set point temperatures, cur- rent load demand, manual/auto control state and output percentage for 6 loops at a time. See Figure 1. Figure 1 5

9 Owner Setup Menu The SETUP button at the bottom of the screen is a quick launch to the Setup Property Sheet which is simply a series of tabaulated screens. See Figure 2. Figure 2 Each Tab contains input cells for the panel operation. For example, temperature, current and override controls are located within the Setpoints tab. Likewise, one may navigate to any of the other tab categories from within the Setup Property Sheet. Navigation notes: 1. Each screen illustrates 6 loops at a time. To make setting changes to loops beyond the current screen within the Setpoints, Tuning, Sensor Mapping (if equipped) or Autocycle tabs, one must select the Loop Navigation buttons in the upper right or left of screen. 2. For most screens, to save your settings, select the OK button. To exit out, select the X button. 3. Auto Test is a Factory tab and is not available to the owner. 6

10 Security Levels & Password Screen After touching the SETUP button, but before the Setup Menu is presented, a pop-up screen requesting a pass- word will appear. See Figure 3: Figure 3 Initial factory set passwords for the below levels of Security are: LevelTitle Code 4. Manager 999 3. Engineering 55 2. Supervisor20 1. Operator 100 Enter the appropriate password and then hit OK to continue to the setup screen. Each of the above Security Levels has predefined accessibility and rights within the programming of the control panel. They include: LevelTitle Accessibility/Rights 4. Manager All customer pages, all passwords and Setpoints editing 3. Engineering All customer pages, Engineering password and All Setpoints editing 2. Supervisor Setpoints, Tuning and Sensor Mapping Tabs & All Setpoints editing 1. Operator Setpoints Tab. Temperature Set Point editing Changes to specific areas within the Setup Property Sheet can only be made once the correct security level code has been selected. 7

11 Setpoints Tab The Setpoints tab (See Figure 4) contains input cells for the following settings for each loop: Customized Naming of each Loop Process Temperature Set Point High & Low Temperature Alarm Limits High & Low Current Alarm Limits Maximum allowable GFEP (Ground Fault Equipment Protection) Alarm Limit Trip and/or Latch Enabled/Disabled (Output permission) upon GFEP Violation Output behavior, whether Automatically or Manually Manual Output Load Percentage (if enabled) Loop Output Override (Enable or Disable Each Loop) Additionally, there exists a Global Setting within the Loop# 1 Grid Apply Globally Setting Figure 4 8

12 Setpoints Tab Navigation notes: 1. Each screen illustrates 6 loops at a time. To make setting changes to loops beyond the current screen within the Setpoints Tab, one must select the Loop Navigation buttons in the upper right or left of screen. Figure 5 illustrates the input cell identification and location for a single loop within the Setpoints Tab: Figure 5 9

Disabled: If the GFEP limit is met, the output is unaffected. Latch (GFEP): Enabled: If the GFEP limit is met, the alarm condition will remain until it is manually cleared. Disabled: If the GFEP limit is met, the alarm condition will be cleared once the GFEP variable is less than the GFEP setpoint Auto/Manual: Select Auto if you wish the Output behavior to be a function of a PID Algorithm or ON/OFF Control (See Tuning Tab for selection) Select Manual if you wish the Output to be driven by a pre-determined Output Percentage. Enter the desired % output. Disable Output: Select this check box if you wish to turn off or disable this loop. Apply Globally: This allows the user to copy all of the settings or Loop Parameters from Loop #1 to all other available Loops. Apply Settings Globally The ITLS/ITAS has a feature which allows the user to apply settings from a single loop to all of the remaining loops within the system. Within Loop #1 on the Setpoints Tab (See Figure 4), complete the input of the parameters and select the Apply Globally button to mirror these settings across all loops. 10

14 Tuning Tab The owner has a choice of how the output is to be operated: Auto, Manual or Off. These selections are made within the Setpoints Tab. If Auto, or Automatic Control Operation is desired, then the tuning of the automatic control is accomplished via the Tuning Tab. See Figure 6. Figure 6 Control Modes: ON/OFF, Tuning Tab Navigation Autotune & PID Notes: Select ON/OFF if you wish the operation of the heat- 1. Each screen illustrates 6 loops at a time.
