Maintenance Timer Display Function
This function indicates that the estimated performance life of the cooling fan and the capacitors on the
PCB board has been reached.
‹ Settings Required to Enable the Maintenance Timer Display Function
Set H2-†† to 2F to use a multi-function contact output for this function and display an alarm on the digital
operator (the parameters U1-61 and U1-63).
„ Multi-Function Contact Outputs (H2-01 to H2-03)
The maintenance time period for the cooling fan or DC bus capacitor can be output from the multi-function
contact terminal by setting H2-†† to 2F. Minor faults will not be output.
* Applicable for Varispeed AC with software versions PRG:1050 or later.
Refer to H2: Multi-Function Contact Outputs in Chapter 5 Parameters and Settings for information on multi-
function contact outputs.
„ Related Status Monitoring Parameters
* Applicable for Varispeed AC with software versions PRG: 1050 or later.
IMPORTANT
The maintenance time periods displayed in the monitors as a percentage to the total life are only an estimate,
not an exact prediction of actual performance life.
Use them as guidelines for replacement.
