In these stages, the pump can be controlled with an external speed control. If the external control signal fails, is it possible to switch on an emergency operating stage. There is a rotary control in the pump, which can be used to set an arbitrary characteristic curve in the power range of the pump. You can download the Delta MIDI manual in our download area to learn more about the PWM function. The PWM control signal is also described in detail here.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As a material, WITA<sup>\u00ae<\/sup> processes cataphoresis-coated armature castings and chromium-nickel steel.
