product detail
Product overview
This series of two-speed fan controllers is a high-performance product specially launched in response to market demand for low-power fans below 22KW. It is mainly used for smoke exhaust, fire control, etc.
Wiring port description
| Terminal number | illustrate | Terminal number | illustrate |
| 1 | Working power supply AC220V live wire | 11 | #Fan fire damper contact/connect normally closed |
| 2 | Working power supply AC220V neutral line | 12 | 2# fan fire damper contact/normally closed |
| 3 | 1# fan contactor coil control point | 13 | 1# fan remote start and stop (automatic state) |
| 4 | 2# fan contactor coil control point | 14 | 2# fan remote start and stop (automatic state) |
| 5 | 1# fan manual feedback point | 15 | 1# fan forced start and stop (any state) |
| 6 | 1# fan automatic feedback point | 16 | 2# fan forced start and stop (any state) |
| 7 | Public terminal (passive) | 17 | 1# fan fault protection point/normally open and normally closed programmable |
| 8 | 2# fan automatic feedback point | 18 | 2# fan fault protection point/normally open and normally closed programmable |
| 9 | 2# fan manual feedback point | 19/20 | 1# fan DC24V fire block starts when power is supplied and stops when power is lost (any state) |
| 10 | Public signal control terminal | 21/22 | 2# fan DC24V fire block starts when power is supplied and stops when power is lost (any state) |
Automatic signal wiring
Fire damper: connected to 8#, 9# and 8#, 10# (connected to normally closed);
Remote control: connect 8#, 11# and 8#, 12# (start when connected, stop when disconnected)
Fire center control (no protection if there is a fault): Connect 17#, 18# and 19#, 20# (DC24V has no positive or negative distinction)
Forced start control (no protection if fault occurs): connect 8#, 13# and 8#, 14# (passive short circuit)
Function selection instructions
Power-off memory saving function
This product has a power-off memory saving function. When the power is turned on again after a power outage, it will default to the state before the power outage. For example: when it is in manual state, the power is off, and when it is powered on, it is in manual state.
Fault type selection
In the automatic state, press and hold the 1# fan start button for more than 5 seconds to switch the fault signal type of terminals 15# and 16#, which are divided into normally open type and normally closed type. The factory default is normally open type.
Protection type selection
In the automatic state, press and hold the 2# fan start button for more than 5 seconds to change the fault protection type of the 15# and 16# terminals to the fault alarm type. It only alarms but does not disconnect the output, and switches the fault protection types in sequence.
