Description
Technical data
Universal electronic control and monitoring devices are used in
single- line and progressive lubrication systems for stationary Function principle universal electronic control
industrial applications, installed in a switching cabinet or internally and monitoring device
Operating temperature 0 to 60 °C; +32 to 140 °F
in a compact lubrication unit. Two different versions are required: Output voltage 24 V DC +10% /-15%
+471 for 100 to 120 V AC and 200 to 240 V AC; and +472 for 24 V DC Connector for class II
Protection class IP 30, clamps IP 20
and 24 V AC. The universal devices can be used as time-dependent Dimensions 70 × 75 × 110 mm
or pulse-dependent controllers. The main task is to initiate a lubrica- 2.7 × 3 × 4.3 in
tion cycle after a set time. The devices also monitor the piston strokes
and run the pump during the lubrication time in clogged operation. Version + 471 100 – 120 V AC; 200 – 240 V AC
Input voltage
All devices have custom- built functions integrated and can be con- Input current rated 70 mA / 35 mA
figured to meet the requirements of the application. Mentioned Power input 8 W
Frequency 50 – 60 Hz
device models must be selected based on their special function con- Fuse max. 6.3 A
figuration and additional features according to the user manual. Switching current max. 5 A
Input voltage sensors 24 V DC
