Behaviour of AHU-CL1

The AHU-CL1 has 2 modes of operation, LOCAL and REMOTE, these can be engaged on the touch screen
controls.

Local mode behaviour

Local mode should only be used when control at the AHU-CL1 is required, this is normally only required
when the system is not fully integrated or during maintenance periods.

When in local mode the inductive sensors that check the positioning of the filter bag and that the AHU-
CL1 is in the correct running location are bypassed.

Remote Mode Behaviour

Remote mode requires integration into a PLC or control circuit to turn the AHU-CL1 on and Off remotely.
There are 2 signals and 1 control signal that come from the AHU.

1.

Filter Blocked Signal

2.

AHU-CL1 Running Signal

3.

Remote Start Stop Control

Remote Star/Stop Control

If the remote start stop signal wires are connected and the AHU is in the correct location the AHU-CL1

will run. if it doesn’t the most likely cause is that the inductive sensors are not engaged, if the AHU-CL1

is not fully back in position or the filter bag is not in the correct location the AHU-CL1 will not run.

Filter Blocked Signal

When the filter is blocked or the AHU-CL1 is in local mode and running out of the machine the filter

blocked warning will come up on the screen. This visual representation will happy instantly when the

pressure set cannot be reached by the AHU-CL1. The signal however does not act the same way, there is

a 30 second delay on the signal on the two signal wires (see wiring Diagram). This is to allow the AHU to

initial get to pressure without giving a warning signal to the PLC, this also removes an intermittent fault

when the AHU-CL1 is at the limit before warning.

The filter blocked % can be set in the settings to allow for the alarm to come on sooner, it is as standard

set at 90% of pump capacity.

AHU-CL1 Running Signal

The AHU-CL1 will turn on and give an instantaneous signal <20mS when the remote start signal has been
given to turn the AHU-CL1.

If the AHU-CL1 has been given the run command and the signal is not seen then there is an issue with
the AHU-CL1 or its positioning is not correct.
