5-2. Overheat Alarm (OHA)
・
If the air inlet port in the top panel or air outlet port in the rear panel is blocked or the PAR-A unit is
used at a temperature higher than the upper limit of the allowable temperature range, the temperature
of exhaust air from the PAR-A unit becomes too high. An overheat alarm (OHA) occurs in such a
case. When an OHA alarm occurs, the MAIN OUTPUT key goes out and all channels are turned
off forcedly.
・
The characters "oHA" are displayed on the current indicator when an OHA alarm occurs.
・
The PAR-A unit is reset to the non-OHA condition automatically if the internal temperature lowers.
(The unit is reset with the MAIN OUTPUT key off. It is reset with the MAIN OUTPUT key on if
the main output is activated through external contact control.)
