| Output mode | 1. When power on, the counter work, reach or exceed the set value, relay switch on. 2. When power on, the counter don't work (can make it work by reset button or reset terminals), reach or exceed the set value, relay switch on. 3. When power on, the counter work, reach or exceed the set value, relay switch off. 4. When power on, the counter don't work (can make it work by reset button or reset terminals), reach or exceed the set value, relay switch off. 5. When power on, the counter work, reach or exceed the set value, relay switch on, when reach to preset reset time, the counter reset automatically, begin work again. 6. When power on, the counter don't work work (can make it work by reset button or reset terminals), reach or exceed the set value, relay switch on, when reach to preset reset time, the counter reset automatically, begin work again. |
