Page 3: Overview
The series DS04 flow meter devices should not be deployed as the sole agents to prevent dangerous conditions occurring in plant or machinery. Machinery and plant need to be designed in such a manner that faulty conditions and malfunctions do not arise that could pose a safety risk for operators. -
Page 4: Installation
Switch point adjustment scale: A scale is applied to the device body, to which the desired switch point can be adjusted. Display scale: On the device, a display housing is mounted with integrated indicator scale and pointer movement. The pointer on the scale indicates the current flow value. - Page 5 This may result in serious injury to the user. if the mediums is contaminated by solids, a strainer must be installed before the device (e.g. SF00 or SF01 from PKP) Direction of flow: Only install the flow monitor in one of the positions displayed in the drawing. The medium must flow in the direction of the arrow (from a low to a high scale value).

Page 6: Connecting Devices Equipped With Reed Switches
Connecting devices equipped with Reed switches Reed switches are basically designed for small contact ratings. To connect a load with higher power consumption it is indispensable to use a contact protection relay (e.g. our series MSR01) If you connect directly a load to a Reed contact the following recommendations should be considered. - Page 7 Lamp Load Lamp loads consist e.g. by light bulbs, starting motors . WARNING: High current spikes at switching on, because the glowing spiral has low resistance at low temperature. Protective measures: (examples) Limitation of current by a resistor or preheating of the glowing spiral.
