5-3. Overheat Alarm (OHA)
・
If the air inlet port in the top panel or air outlet port in the rear panel is blocked or the PW-A unit is
used at a temperature higher than the upper limit of the allowable temperature range, the
temperature of exhaust air from the PW-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 PW-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.)
