Initial Test
As well as routine inspection it is also important to test the installation when first commissioning.
The below will advise how to perform either a Test On Load (TON) or Test Off Load (TOF).
TON is the recommended option however, due to site requirements at the time a TON may not be possible.
TEST ON LOAD will cause a load supply interruption when testing the transfer function as the
load will change from one source to another in open transition.
Test On Load (TON)
TEST ON LOAD / LOAD TEST: will perform a full test including all the timers and operating the switch (full cycle).
As default the Test Button will preform a TON.

A TON will start by sending a start-gen signal to the secondary source (if in Main-Gen), and will initiate a
transfer to the secondary source.
To finish the TON Press the Test Button again and confirm with the OK button,
once the test has ended the switch will transfer back to the priority source.
Test On Load (TOF)
TEST OFF LOAD: Initiates starting of the genset but will not give the order to transfer to the secondary source when it
becomes available.
