Connecting the AC Line Voltage (Main Voltage)
The SPS-50 is designed to provide back-up power to the gate
operator ONLY. Auxiliary devices such as loop detectors, card
readers, phone entry systems, etc., must NOT be connected to
the output of the SPS-50. These devices may overload the
capacity of the SPS-50 and prevent proper gate operation.
Electrically, the SPS-50 is wired in series with the incoming AC
supply from the breaker box to the operator. The connector
labeled AC IN is connected to the main AC supply. The AC
OUT is connected to the operator.
Refer to the diagram on page 7 for the following:
Connect the incoming AC line to the AC IN as follows:
L - AC Line In (live): Black
N - AC neutral (common): White
G- AC Ground (earth): Green
Connect the outgoing AC line to the AC OUT as follows:
L - AC Line out: Black
N - AC neutral: White
G- AC Ground: Green
Refer to the instructions provided with the operator for the
proper connections to the operators.
Connecting the Relay Outputs
Two sets of relay outputs are available on the SPS-50. The set
marked LO BAT are intended to be alarm contacts to alert of
low battery capacity. These must be connect to a suitable alarm
system (not provided).
The set marked RELAY are connected to the operator as
follows:
CM - Common, connected to the control input common terminal
of the operator
NO - Normally open, connected to the hold open terminal of the
operator
If the operator uses a normally closed control circuit, the NC
contact may be used. Refer to the instructions provided with the
operator for the proper connections to the operator control panel.
Applying Power and Connecting the Battery Pack
Follow the steps below when connecting the battery pack to the
SPS-50:
1. Turn the main power on. The AC LED on the SPS-50
should be on.
2. Test the operator for several open / close cycles
3. Connect the battery pack to the SPS-50. Connect the red
wire to the red terminal on the batter pack and the black
wire to the black terminal on the battery pack
WARNING!: Do not reverse the connections to the battery
pack. Reversing the leads will permanently damage the SPS-50.
Typically, the batteries will require 24 hours of charging time
after installation.
Testing the SPS-50
After the batteries are charged, the SPS-50 may be tested. To
test, turn the main power off and allow the SPS-50 to cycle the
operator. There will be approximately a ten second delay
between the loss of AC power and when the operator starts to
open. After approximately 30 seconds, the SPS-50 will shut
down the power to the operator.
After the completion of the test, turn the main AC power back
on. After approximately ten seconds a reset pulse will be sent to
the operator. If the operator is wired for auto timer to close, it
should close at the end of the time delay period.
The SPS-50 will only provide back-up power for 2-5 cycles
(depending on battery charge, temperature and gate size and
weight). If the battery charge is too low, the SPS-50 will not be
able to develop sufficient voltage to power the gate operator and
the batteries must recharge before additional testing.
A monthly test should be made to ensure proper operation of the
system.
INSTALLING THE SPS-50
RISK OF ELECTROCUTION. DO NOT BEGIN
THE ELECTRICAL CONNECTION
PROCEDURES UNTIL THE POWER IS TURNED
OFF AT THE CIRCUIT BREAKER.
WARNING! DO NOT CONNECT THE BATTERY PACK UNTIL
