RS Control Panels

The RS 301K and RS 400K are for swing lip levellers, and the RS 301V and RS 400V are for telescopic lip.

An LCD programmer is essential for the RS 300 and RS 400, all features are accessed by the programmer. The advantage of using a programmer is that it prevents unauthorized access to the setup menus.

Unfortunately, the timing functions required for this valve sequence are not available on the RS 400K. In this case, we can only offer the RS 301K, so a separate door controller is required.

The RS 301V and RS 400V both have 8 telescopic valve sequences, there are five 3-valve options and three 2-valve options. We rarely find a telescopic valve sequence that isn't possible with these controllers.

This occurs because the panel cannot see a lip or park switch. The RS 400 uses lip/park switch for interlocking the door controls while the leveller is deployed. It is essential for lip-in and auto-return functions. This message could be displayed because the lip/park switch has failed or the switch has not been fitted on installation. The lip/park switch must give a closed circuit when the lip is fully retracted/parked. The message is usually displayed when the door is closed.

This can happen because the lip-in switch is faulty, if the fault occurs on installation, it is usually because the installer has linked out the lip switch terminals rather than fitting a switch to the leveller. A lip-in switch must be fitted.

The external traffic lights need to be turned on in the INPUT menu, (TR LIGHTS OUT)

There is a selector switch on the front of the RS 400 that activates the automatic inflation of the shelter. Make sure this is switched on and the LD7 light is illuminated. The shelter should inflate when the door opens. Also, try reversing the polarity of the shelter control wires.

The RS 400 has a wheel block function that takes a signal from a wheel block or castell lock. On activation the traffic lights switch, then door and leveller operation are enabled. One of the programmable relay outputs can be used to indicate that the door is closed to allow the removal of the wheel block at which point the traffic lights will revert to green allowing the vehicle to depart.

A driver's button can be connected using the wheel block function. We offer a driver's button modification to the RS 400 to save the installer time on site.

Unlike the CS controllers, the RS 400 will not power up in ADJUSTMENT mode when the limits are not set. This fault occurs because the limits are not set. By setting limits, the fault will be rectified.

This fault is shown because the panel cannot see an encoder. It could be due to a wiring error but usually, it is because the RS 400 is being used with mechanical limits. In this case, the limit type needs changing in the INPUT menu.

The RS 400 is designed to work with the Kostal (DES-B) encoder or mechanical limits.

The internal traffic lights do not mimic the external lights. They are a "ready to load" function that works in conjunction with the lip/park switch. The green light will activate when the leveller is resting on the vehicle. If you want to mimic the external lights, you can use the external light terminals assuming the lamps are rated for the same voltage. Otherwise, the programmable relays could be used to switch the internal lights.

RELAY 2 can be used to switch a dock light. No programming is required as the relay is pre-programmed to switch on when the door is open.

When the door reaches the close position there is a 20 second delay before the external traffic light changes to green to allow the shelter to deflate. A delay can also be set to allow the shelter to inflate before the door opens, this is particularly useful in refrigerated installations.

On some sectional doors the cables are configured so that the drive shaft turns in the opposite direction to what the RS 400 expects. This can be rectified by altering the Rotating Field parameter in the INPUT menu, now the RS 400 expects to see the encoder turn in the "wrong" direction.
