CONTROLLING THE LOAD BANK WITH THE iHHC3 CONTROLLER
Select the appropriate load using the iHHC3 hand held controller as follows;
1. The hand held controller counts down from 7 to 0
when first powered up and displays:
a. Number of multiple Load Banks that can be
linked together and controlled from the single
controller.
b. Maximum Load - this is the maximum kW
load of one or multiple load banks linked
together.
c. Run kW - this shows the running load of the
load bank.
2. Set the required kW load using the X1, X10 and X100 buttons and press the
green ACCEPT push button.
3. The controller will display the accepted load in “ running mode “
4. The load can be adjusted on the ‘fly’ by pressing the black buttons to increase
and decrease the load in 1kW steps for each button press.
5. New load profiles can be set by pressing the X1 , X10 or X100 push buttons
and accepting or reverting ( yellow button ) back to the existing load.
6. The load can be disconnected from the power source in two ways
a. SLOW STOP – orange push button this feature removes the total load
in sequence, in a few seconds.
b. QUICK STOP – red push button this feature removes the total load
instantaneously.
7. At the end of the test the load bank should be run off load for between 5 and
10 minutes to cool the resistor elements.
8. Only isolate the UPS or generator power source when the load bank is
switched off.
9. DO NOT remove the power circuit with the load circuit energised.
The red EMERGENCY STOP button can be used as an Emergency Disconnect at
any time during a test to disconnect all load circuits and the fan supply.
