Function

The LA-4 ventilation power supply unit can be used to control one or two 24 V motors. The control has an internal overcurrent cut-off per output. The value of the cut-off can be set with the first three DIP switches. The two 24 V drives are switched off at an adjustable load current of 0.55 A /0.8 A / 1.1 A / 1.5 A or 2.0 A. In addition, a setting can also be made in which 4.1 A can be tapped at motor output 1. In this operating mode, motor output 2 has no function.

Synchronous operation

Only in cooperation with the drives JM-DC-SYN-XX. Here, two drives are controlled synchronously.

Tandem operation

The two motor openers run in dependence. If the first motor stops in the "open" direction, the second is also stopped immediately. In the "closed" direction, the second motor can run for up to 5 seconds before it is also stopped.

Solo operation

The two motors run independently of each other.

Single operation

Only one motor is connected to output 1.

The ventilation control can be selected with DIP switch 6.

With phase control, the drives run as long as the phase is present at the input and the motor has not reached the end position. For control via the potential-free changeover contact input, 230 V AC must be applied to the "Open" phase (L-"Open"). DIP switch 7 now decides between momentary and continuous operation. Generally, both motor outputs are always in the same ventilation group.

If you want to learn some - admittedly very technical - background about power supplies, in this blog post we will show you the difference between regulated and unregulated power supplies and possible effects on the connected drives.
We show you what you have to pay attention to when you want to connect 24V drives to 230V.
What's the difference? Most people can imagine solo operation, but what is the difference between tandem and synchro operation?
