ACOAS-ADS-VFC - Automatic Duty Share Changeover panel

£ 143.00 (excl. VAT)

£ 171.60 (inc. VAT)

The ACOAS changeover panels are designed to suit single phase twin fan units with airflow switches. Please note that an airflow switch must be fitted to monitor each fan and the airflow switches must not “see” the airflow from the other fan I.E. the 2 airflow switches cannot be in the same airstream.
The control panel fascia has a power lamp, fan fail lamp and a rocker switch. The VFC models have fail contacts that can be used in conjunction with a remote indicator or to interface with a building management system.

Installation:
Check that the auto changeover panel supplied is compatible with the fan motors. Install in a dry sheltered position. Do not install in close proximity to a heat source. Remove the front cover of the controller by unscrewing the fascia fixing screws. This provides access to mounting holes and electrical terminals. All wiring must be carried out by a suitably qualified and competent person and comply with current applicable regulations.

Auto Changeover:
The control panel will automatically changeover from the duty fan to the standby fan if the fuse (within the auto changeover panel) for the duty fan ruptures.
Manual duty share models:
Manual duty share models are fitted with a 2-position (Fan A/Fan B) rocker switch enabling the user to manually select the duty fan. The control panel will auto changeover from the duty fan to the standby fan as described in Auto Changeover above.
Auto duty Share models:
Auto duty share models are fitted with an electronic timer to provide a 12 hour cycle time for each fan.The timer has a jumper link to allow testing of the auto changeover on a 1 minute test cycle for each fan. After testing the jumper link should be fitted back in the 12hr cycle time position. The position of the jumper link for the test cycle and 12 hour cycle are shown below.
Volt free contacts (VFC models)

These models are suffixed with VFC and feature 2 sets of volt free contacts, 1 set for a common fan run status and 1 set for a common fan fail status. The contacts are normally open and close when either fan is running or has failed.
