| Diagrams 1, 2, 3a-3b (connection of electric motor in the fan`s service switch) |
| Lock the switch in position ON to prevent unintended switch OFF (lock is not in scope of delivery) |
| PS = Power supply (user) |
| Motors are without PTC. Thermal protection by user. In case of fire thermal protection must be bridged. |
| Depending on motor 3, 6, 8 pole switches with NO+NC are used. See details in instruction. |
| Diagram 1: M = 3~ AC motor with P2 <=4 kW. Starting method: direct start (DOL). |
| Diagram 2: M = 3~ AC motor with P2 >=5,5 kW. Starting method: power supply in delta (D) connection at direct start (DOL). |
| Diagram 3a: M = 3~ AC motor with P2 >=5,5 kW. Starting method: star-delta starting (Y-D). PS in star (Y) connection at start only. |
| Diagram 3b: M = 3~ AC motor with P2 >=5,5 kW. Starting method: star-delta starting (Y-D). PS in delta (D) connection at operating. |
| Diagram 4: Functions and connection to actuator`s control box |
| Diagram 4a: Functions of the actuator`s service switch (NO-NC switch position control): |
| Position 0: stop (NO - opened contact, NC - closed contact) - SAFETY POSITION |
| Position 1: open hatch cover (NO - closed contact, NC - opened contact) - WARNING! |
| Position 2: close hatch cover (NO - opened contact, NC - closed contact) - DANGER! |
| Diagram 4b: Connection of power supply to actuator`s control box |
| Power supply L1 and L2 must be of the same AC source, frequency and phase shift! L1 and L2 must not be L1 and L2 of 3~ system! |
| Power shall not be supplied simultaneously to line L1 and L2. |
| Minimum time of 15 s pause required before changing the direction via L1, L2 or service switch (L1 - 0 - L2 or vice versa). |
| The control voltage L1 or L2 to open or close hatch cover should apply max. 6 minutes. |
| This is to ensure by control system (use actuator`s internal floating limit switches as indication of cover position to cut off the control voltage). More see instructions (current, intermittence). |
| Operating mode for peak load at 25°C ambient: S2 1 min. |
| Operating mode for continuous load at 40°C ambient: S3 5% (example: open in 30s, then wait 9min 30s). |
| Max. current of actuator(s) at SL 1000 (rated MRH load): 1,6 A (3,2 A at sizes 1120 and 1250). |
| Diagram 4c: Connection of actuator`s internal floating limit switches in the actuator`s control box to control hatch cover position |
| Drawn position - closed hatch (terminals 4, 5, 6 at MRH 1120-1250 only) |
| 1-2 opened, 2-3 closed in closed hatch position |
| 1-2 closed, 2-3 opened in opened hatch position |
| 1-2 closed, 2-3 closed in any intermediary position of the hatch cover |
| 1-2, 4-5 opened, 2-3, 5-6 closed in closed hatch position (MRH 1120-1250 only) |
| 1-2, 4-5 closed, 2-3, 5-6 opened in opened hatch position (MRH 1120-1250 only) |
| 1-2, 4-5 closed, 2-3, 5-6 closed in any intermediary position of the hatch cover (MRH 1120-1250 only) |
| Potentialfree NC contacts, load capacity 24VDC/1A |
