Multi-Timer English
Performing a visual check
Perform a visual check after the assembly of the module and remove
faults if necessary:
 Remove all loose parts, wire ends or drops of solder from the PCB.
Remove all sharp wire ends.
 Check that solder contacts which are close to each other are not
unintentionally connected to each other. Risk of short circuit!
 Check that all components are polarised correctly.
When you have remedied all faults, go on to the next part.
7. Connecting the Multi-Timer
Functional test
Especially, when you have mounted the Multi-Timer from a kit, you
should perform a functional test before mounting it in your layout.
Connect an electric bulb with a separate power supply to output 1 and
a push-button to switching input 1 as described below for operation
mode 1. Connect the Multi-Timer to the power supply.
Choose operation mode 1 (r) for testing all outputs, so do not insert a
jumper to any of the solder pins. Set a short switching time (trim-pot as
far as it will go to the left). Then check all four outputs and switching
inputs one after the other.
Caution:
When a component gets hot, disconnect the module from the power
supply immediately! Risk of short circuit! Check the assembly!
