5 GHL Control Center Startup Screen Explained Before even connecting to your device, this section will explain what GHL Control Center is used for and the important options displayed in the GHL Control Center (GCC) startup screen. What is GHL Control Center? GHL Control Center (GCC) is the platform that is used for programming GHL Devices. GCC allows you to connect to devices to perform firmware updates as well as setup basic and advanced functions. 1. These are your connection options. When connecting to your Doser, make sure you have the correct device selected before clicking connect. 2. Buttons for connecting to the selected device or making changes to the connection settings. Connect: Click to connect to the selected device Administrator: Click to add a new connection or modify an existing one. 3. This is the screen that pops up when you click on Administrator. It will display all your current connections to various devices such as ProfiLux, GHL Doser 2.1, and Mitras LX LED. 5

6 GCC Overview for GHL Doser SA GHL Control Center gives you the flexibility to program the Doser SA in multiple ways. We have included multiple screenshots to show the general features and an overview of our PC software. (General Overview Page) 1. This is the drop-down section which is where most doser functions are performed. General: The general overview of your doser as shown in the above screenshot. Processes: The section where you can set timer functions for ATO and AWC. Dose Overview: Program your doser pumps from this section. The drop-down will show all 16 dosing pumps. Probe/Sensor Controls: Program your ATO and AWC functions from this section. System: Doser systems settings can be accessed here for Wi-Fi/LAN settings, PAB configuration, and myghl settings. 2. The current firmware version and date will be displayed here. 3. If you have a GHL temperature probe (PL-1115), current temperature will be displayed here. 4. You can set your Alarm to be audible or silent. 6

7 (Timer Settings Page) 1. Set your timer functions for AWC and ATO functions here. 2. Control how you want the timers to function here. 7

8 (Dosing Pump Programming Page) 1. GHL Doser SA will monitor your fluid levels and display it here. Once the specific dosing pump has been programmed, the doser will automatically calculate the approximate amount of days remaining before you run out of fluid for that pump. Container capacity and remaining fluid is also displayed here. 2. Container capacities for each dosing container can be set here. You also have the option to set the minimum threshold for when the GHL Doser SA should notify you that you are running low on fluid. When the container needs a refill, you can click on Refill Container and enter the amount of fluid added to the container. 3. If you wish to manually dose, you can do so by clicking on the picture of the doser head. You can also specify the amount you want to manually dose by clicking on Dose Now. 4. The GHL Doser has the option to run at 3 different speeds: Slow, Moderate, Fast. Each time the speed of the pump is changed, it MUST be recalibrated. After calibration, the new amount of fluid dispensed is entered into this section. 5. This section will allow you to tell your selected dosing pump how to react. For example, if you wanted to use this pump as an ATO or AWC pump, you would select Level Control. 8

9 (Dosing Pump Programming Page Cont.) 6. Set how you want to run the doser. Auto Dosing: Auto dosing allows you to tell the doser how many times per day to dose and how many ml each dose will consist of. For example, 5 dosings per day at 10ml per dose will dose 50ml per day. Once the amount has been set, the GHL Doser will evenly dose the total specified amount evenly throughout the day. Up to 150 doses per day and 200ml at a time is the maximum amount. Manual Dosing: Manual Dosing allows you to set the times to dose, on what days or how often, and how much to dose at that specified time. You may set up to 8 doses with this setting. 7. This option is available for both Auto and Manual dosing. From here, you can specify the exact days you want a specific doser pump to run or in what intervals. For example, you can set the doser pump to dose every 3 days by selecting 3 days in Repeat all. 8. Available only for Auto Dosing mode. You can tell the doser how many times per day to dose and how many ml each dose will consist of. 9
