Installation
5.5.4. Pulse output isolator
5.5.5. Additional ventilation 115 / 230 V
The pulse output isolator allows any device to be securely
connected to a pulse output.
The pulse output is a voltage free output. The isolator is not
necessary when the output is connected to a 38 39 40 41 pulse
input of another Dostec AC.
6. START-UP AND REGULATION
FIXING: Check that the pump is properly secured
OIL: Check the oil level using the side sight glass
Replace the transport fill cap for transport with the working one.
HYDRAULIC CIRCUIT CHECK: Check that all valves are open, and that the bleed and relief valve
outlets are diverting the liquid to a container.
PUMP CHECK: Make a visual/auditory check of the correct operation of the pump.
PRIMING: To facilitate pump priming, especially with low flows when there is no priming valve, it is
advisable to minimize the pressure in the ejection line. Another option is to fill the head cylinder and
suction pipe with liquid.
OVERPRESSURE PROTECTION: Adjust the safety, overpressure or pressure relief valve to the
desired pressure to protect the installation, while never exceeding the nominal pressure of the pump.
This option is recommended for continuous operation at temperatures above 40 °C (104 °F) up to a
maximum of 50 °C (122 °F)
