PRODUCT DESCRIPTION
e DRX/DRY controller controls manually the speed of single phase (230 VAC / 50 -
60 Hz) voltage controllable motors / fans from high to low (DRX) or from low to high
output (DRY). It is suitable for DIN rail mounting (DIN EN 50022). Multiple fans can
be connected as long as the current limit is not exceeded.

MOUNTING & OPERATING INSTRUCTIONS IN STEPS
Before you start mounting the DR speed controller, read carefully “Safety and
Precautions”. Then proceed with the following mounting steps:
1. Switch off the power supply.
2. Mount the controller on a standard 35 mm DIN rail. Pull the locking clip before
you place the unit onto the rail, and then release the locking clip back to its original
position to fix the enclosure to the rail. See Fig. 1 DIN rail locking clip, Fig. 2 Mounting
dimensions and Fig. 3 Mounting position.

cover. Adjust the minimum speed with the trimmer (if necessary). e factory
preset is 100 VAC. See Fig 1.
VERIFICATION OF THE INSTALLATION INSTRUCTIONS
When you switch on the power supply the LED for operating indication shown in Fig. 4
should give out constant green light. If this is not the case, check the connections.
