 # XY-FZ25 & XY-FZ35 Electronic Load Control Program

Instruction manuals for those devices can often be found on the resellers web sites.

 A **programmable electronic load** emulates DC or AC resistance loads required to perform functional tests on batteries, all sorts of power supplies, solar cells, technical equipment, etc. There are many other useful scenarios.
 In the simplest case an electronic load just sinks current (absorbes power). The amount of current can be set and the load tries to keep it stable even when the applied voltage changes.  
 
-The XY-FZ25 is limited to 4A/25W and the XY-FZ35 to 5A/35W. That doesn't sound much but really is enough for most cases.

 ## :zap: The Control Program
 
 The program "Electronic Load" in folder [**Program**](https://github.com/yellobyte/ElectronicLoad_Control_XY-FZ35/tree/main/Program) does **display** live readings in a chart. Furthermore it can:  
-- **save** charts to hard drive as **data file** (_.eld_), **bitmap file** (_*.bmp_) or **csv file** (_*.csv_)
+- **save** charts as **data file** (_.eld_), **bitmap file** (_*.bmp_) or **csv file** (_*.csv_)
 - **print** charts
-- **load** previously saved charts (_*.eld_ data files) from hard drive, which gives you the easy ability to compare the final test results of various batteries/accumulators/etc later on
+- **load** previously saved charts (_*.eld_ data files), which gives you the easy ability to compare the various test results later on
 
 If you **associate** _*.eld_ files with this program you only need to double click them to see saved charts.

 Additionally the load will monitor various definable parameters and trigger an alarm plus turn itself off if required:
 
-- **LVP**...Low Voltage Protection: When the load voltage drops below a set value. This is important for discharge tests in order to protect the accumulator/battery.
-- **OAH**...Maximum Discharge Capacity: When the load reaches a defined accumulated discharge capacity (in Ah). This feature too is for protecting the accumulator/battery when doing discharge tests.
-- **OHP**...Maximum Discharge Time: When the runtime reaches a set timespan. Important for discharge tests that need to run for hours or even days.

 ### :heavy_exclamation_mark: Important
 Don't forget to **set the correct hardware version** of the device before controlling it (Settings->Hardware Version->25W/35W) !  
 
 ## :information_source: Installation
 Depending on your Windows architecture copy the 32bit or 64bit version of the executable into a program folder and that's basically it.  
 
-In case you get a windows error message trying to run the program (like "mfc140u.dll missing" or similar) depending on your Windows installation you additionally need to install the **Microsoft Visual C++ Redistributables 2019 (x86/x64)** or higher. Those packages are easily available on Microsofts websites, as of today (02/2022) from [here](https://docs.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170) for example.

+- **OPP**...Over Power Protection: When the power it absorbes gets greater than the set OPP power limit.
 
-- **OVP**...Over Voltage Protection: When the load voltage is higher then a set value.

+**Please note:**  
+Some alarms (OPP, OAH, OHP) can't be cleared via serial communication. In such cases the On/Off Button on the device itself must be pressed to end the alarm and get the device operational again. Message Boxes will tell you if that's the case.
