(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
(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

Solution: Check possible issues noted below Please note that there are two Wi-Fi connection options. For more information, see GHL Doser 2.1 SA Connectivity Options If trying to connect via Standard Wi-Fi Connection: Make sure the device you will be using to connect to the doser is also connected to the same Wi-Fi network. Make sure you ve entered the exact IP address you assigned to the doser into the Host box of the app or GCC s connection settings. If you let your network automatically assign an IP address for your doser, you must know what that IP address is by logging into your router settings and viewing the IP address map. Make sure the doser s Wi-Fi settings match your Wi-Fi network s settings When you setup the doser s Wi-Fi settings it is very important to put in the exact details of your network, otherwise there will be connection problems. If you are unsure on how to find the details of your network, please refer to the Tips and Information section. Tips and Information How to find the details of your Wi-Fi network These tips are useful if you are having trouble connecting to your doser via Standard Wi-Fi connection and need to confirm the details of your network. It is especially important to make sure your network s Wi-Fi details have been entered correctly into GHL Control Center. 1. Type into your windows search bar, cmd and select windows command prompt. 2. In command prompt, type in ipconfig and press enter. a. You will then see various pieces of data. Do not worry about the whole data as we are only using two pieces of it. 3. Take a look at Subnet Mask and Default Gateway and write it down. 48
a. This is what you should be looking for: b. The image above is for illustration purposes ONLY. Each network has its own unique data. 4. Confirm that these two fields are typed into the Doser s Wi-Fi settings EXACTLY as it is shown in your command prompt Wi-Fi data result. Assigning a correct IP address During Standard Wi-Fi connection setup, when you are asked to select an IP address, make sure you select a number within your network s DHCP range. This range is commonly provided by GCC during the setup steps. If you decide to not use the IP settings setup wizard, make sure that the first 3 IP address fields are the same as your Default Gateway. For example, if your Default Gateway is 192.168.1.1, you MUST fill in the first 3 fields into the assigned doser IP address, 192.168.1.xxx - The last field can be a number that is not assigned by another device on your Wi-Fi network. Confirming doser connection to your network via LAN or WiFi 1. Type into your windows search bar, cmd and select windows command prompt. 2. Type in Ping (YOUR DOSER S IP ADDRESS GOES HERE), press enter. For example, if your doser s IP address is 192.168.1.150, to ping it, type in Ping 192.168.1.150 3. Successful communication to your network will result in the outcome below. 4. If this does not show, you may want to assign a new IP address to your GHL Doser 2.1. 49
