- Changeover Panels for Twin Fan Units
 

ACO/TO/AS


For use with single or three phase twin fan units with airflow switches and/or motors without TK contacts.


The ACO/TO/AS is designed to suit single or three phase twin fan units fitted with airflow switches and/or motors with no TK protection. The control panel incorporates 2 industrial contactors fitted with thermal overloads pre-set to your requirements. The control panel features a 2-position rocker switch for FAN A/ FAN B and neon indicators for power and fan fail. The unit will automatically
changeover to the standby fan if the airflow switch of the selected fan closes or if the thermal overload of the selected fan trips. Auto Duty Share
Version available.
 

ACO/TK

For use with single or three phase twin fan units with motors having TK (thermal contacts) protection.


The ACO/TK is designed to suit single or three phase twin fan units using motors with TK (thermal contacts) protection. The control panel includes an OFF/FAN 1/FAN 2 rocker switch and fan run and fan fail neon indicators for each fan. The unit will automatically changeover to the standby fan in the event of the TK contacts on the selected fan opening.

 

ACO/FR/AS

For use with single-phase twin fan units up to 8 amps with airflow switches and/or motors without TK contacts.

The control panel features a 2 position FAN 1 / FAN 2 rocker switch and neon indicators for power, and run and fail indication of each fan. The unit will automatically changeover to the standby fan if the airflow switch of the selected fan closes or if the control panel fuse for the selected fan ruptures. The control panel can be switched on and off from an external voltage signal, and with the addition of an optional plug in pcb can be transformed into an Auto Duty Share version with changeover times of 2 minutes (test) 6 hours, 24 hours, and 1 week.

Speed Controllers


With the exception of the ACO/AS & ACO/FR all CADAMP changeover panels can be used in conjunction with speed controllers (when using three phase motors a transformer type speed controller is required).

ACO/FR

For use with single-phase twin fan units up to 3 amps without airflow switches.

The control panel features a 2 position FAN A / FAN B rocker switch and neon indicators for power, and fail indication. The unit will automatically changeover to the standby fan if the control panel fuse for the selected fan ruptures.
 

ACO/AS


For use with single phase twin fan units up to 3 amps fitted with airflow switches.

The control panel features a 2 position FAN A / FAN B rocker switch and neon indicators for power and fail indication. The unit will automatically changeover to the standby fan in the event of the airflow switch of the selected fan failing (contacts closing).
 

ACO/TK/ADS

Automatic Duty Share Changeover Panel for use with twin fan units withn motors having TK (thermal contacts) protection.

The ACO/TK/ADS is designed to suit single or three phase twin fan units using motors with TK (thermal contacts) protection. The control panel includes an ON/OFF rocker switch with fan run and fan fail neon indicators for each fan. The panel has an adjustable time auto duty sharing facility. A miniature DIL switch enables the duty share time to be set at 2 minutes (test), 6 hours, 24 hours or 7 days. The unit will also automatically changeover to the standby fan in the event of the TK contacts on the selected fan opening. The panel also features volt free contacts for connection to remote run and fail lamps (Can be linked to E.M or B.M.S systems to show fan status).
