11. Power Supply Connections - PSF-249 (10 Amp)
Indicator Green = Supply Healthy Amber = Fault
When the Green light only is illuminated, the unit is operating normally with
supply to the load and the batteries (when fitted) are receiving charge current.
When the Amber light is illuminated at the same time as the Green light there is a
fault on either or both of the output supply and the charge supply. If the Green
light is NOT illuminated, the mains supply is not present.
PCB Fuse: FS.2. = 2 Amp (20mm x 5mm) Output Fuse: Standard automotive =10Amp
PCB Indicators:
Amber LED 5 = when lit indicates battery not connected or mains fail
Green LED 6 = when lit indicates ‘real’ battery charging in progress
Green LED 2 = when lit indicates the output is present.
Green LED 3 = when lit indicates the mains supply is present.
Amber LED 1 = when lit indicates there is an output fault/blown fuse.
Red LED 4 = when lit indicates there is a remote trigger input.
Battery Connections
Two batteries (typical types to be used are Yuasa NP12-7) in equal state of charge are
required to make up 24V. The supplied leads should be used.
Battery Cut-Out
During A.C. failure the system will switch to battery standby, the output voltage level
will follow that of the batteries down to approximately 19V. At this point the cut-out
circuit for battery protection will disconnect power altogether. Should A.C. not be
available when testing with healthy batteries, a quick short on J11 pins will activate the
battery cut-in to power the load. (if there is sufficient charge in the batteries)
Fault Relay
The fault relay output will go from normal to fault state when A.C. power is removed or
when there's a fault in the unit as indicated by LP5 or LP6..
12. Indicators – AOV pcb
Green LED 6 - Right hand relay pcb - lit in normal operation, off when “trigger”
present
Green LED 2 - Left hand relay pcb - lit when output 24v present
Green LED timer LED 1 - lit when timer is active upon actuator closure.
Green & Amber LED 3&4 – Actuator status.
13. Actuator timing setup
Using the jumper provided, junctions J5, J6 and J7 will provide the following
time scales when in reverse polarity:
J7 = 0 seconds – 1 minute
J6 = 1 minute – 2 minutes
J5 = 2 minutes – 3 minutes
Note: These time scales are adjusted using VR1
