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

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/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).
