MAKING BASIC CONNECTIONS
1. OVATION CONTROLLER CONNECTIONS
NOTE:
Refer to Tables 1-4 for wire sizes and run distances for the following procedures.
A. Door/gate control
Refer to Figure 12 and connect the wires from Ovation-controlled devices as follows:
!
Relay/door 1
TB 5
!
Relay/door 2
TB 6
Which terminals are used depends on the type of device being controlled:
♦
Dry Contact Closures (most gate operators):
Connect one wire to the NO terminal and the
other to COMMON.
♦
Normally Locked Strikes:
Connect one wire from the strike power supply to the NO terminal
and one wire from the door strike to COMMON on the same terminal block. Connect the
remaining wires from each source off the board with a wire nut.
♦
Magnetic Locks and Normally Unlocked Strikes:
Connect one wire from the power supply
to the NC terminal and one wire from the door strike to COMMON on the same terminal block.
Connect the remaining wires from each source off the board with a wire nut.
NOTE:
Magnetic locks and DC powered strikes produce potentially damaging voltage spikes.
Sentex strongly recommends installing an IN4001 diode across the magnetic lock coil
with the cathode (the banded end) connected to the positive side of the coil, and the
anode connected to the negative side of the coil.
B. LIB Control:
♦
Single Unit Installations:
Plug the 4 twisted pair cable from the Ovation converter board into
TB1 on the connector board in the first LIB housing.
♦
Multiple Unit Installations:
Plug the 4 twisted pair cable from the Ovation converter board
into TB1on the MUI in the first LIB housing. Plug the four twisted pair cables from additional
Ovation controllers to the corresponding unit numbers on the MUI.
NOTE:
The MUI can accommodate up to four Ovation controllers.
C. Ovation Controller Power
AC POWER
: Connect the two wire shielded cable cable to TB8 on the Ovation main processor
board (polarity is unimportant) and to the transformer provided with the system.
DC POWER:
Connect one end of a two wire shielded cable to TB8 on the main processor board
(polarity is unimportant) and the other end to the DC power supply.
♦
DC Power
must be at least 13.5 Volts.
♦
UPS:
Since the Ovation will not charge a battery, DC power must be supplied by an
uninterruptible power supply.
♦
Line Loss:
If system and power supply are too far apart, line loss may result in inadequate
voltage being delivered to the system. Refer to Table 1 for wire sizes and distances.
CAUTION: High voltages are present in the power supply area of the controller board when
power is connected. Do not apply power until all system connections have been made.
When power is applied, the Power indicator on the bottom left of the Ovation board will light.
