- adjustable pickup delay tv
- with or without latching, switchable
- Test / reset button for easy commissioning and as setting aid
- up to 40 A without external current transformer
- Working current principle (output relay activated in case of fault) or resting current principle (output relay not activated in case of fault)
- Switchable optionally for single-phase loads LED indicators
- 45 mm width
Application
The load monitor is suitable for monitoring electrical industrial drives with variable motor load. Design and function: The load monitor BH 9097 monitors the active power consumption of electrical loads. Due to the single-phase measuring principle, symmetrical loading of all 3 phases is assumed, as is usual with motor loads. Using DIP switches, the device can be configured as underload and overload monitor P1 min / P2 max. or as overload monitor with pre-warning stage P1 max. / P2 max. The settings for P1 and P2 are calibrated as absolute values in watts and are made via two rotary switches. 2 LEDs indicate the switching state of the associated output relays. The relays can be configured for working current or resting current principle. Each relay is affected by a separately adjustable pickup delay tv and a jointly adjustable startup override ta.
Measuring current (see table): A, C, E
| Measuring range | A | B | C | D | E | F |
|---|---|---|---|---|---|---|
| Rated current A | 40 | 24 | 8 | 2,4 | 0,8 | 0,24 |
| Continuous overload | 0...40 | 0...40 | 0...16 | 0...8 | 0...4 | 0...1 |
| Overload 1 min. (10 min. pause) | 150 | 150 | 20 | 16 | 3 |
