Optional Equipment
The following optional items are available for your 885
Operator.
Slave/Relay Card
The 885 Slave/Relay card is a device that allows you to
obtain the following features.
1)
Slave: Enables two opposing operators to
operate simultaneously, preventing any lag time
between the gates when a signal is sent to the
operators to open.
2)
Relay: Provides eight normally open (N.O.)
contacts for connecting extra equipment, such
as lighting controls, counters and so forth.
The slave/relay card plugs into the master 885’s control
panel (J1).
Plugging the card into the master 885 control panel and
then wiring the two boards together as shown in Figure 9
achieves the master/slave configuration.
The slave will then react as the master does.
The following things must be done in the programming
stages to insure the proper operation of both the master
and slave operators.
1)
The master unit
must
be installed on the longer
leaf.
2)
Set the
slave
unit time out equal to the time set
on the master.
3)
The safety devices must be connected to the
master
unit.
4)
Program the following function on the
master
operator.
“Stand Alone” AL Y
“Slave” SL N
5)
Program the following function on the
slave
operator.
“Stand Alone” AL Y
“Slave” SL Y
6) If you are in “A” mode and have a jumper
placed between terminals two and five than set your
slave machines pause time to 00 Seconds.
Note:
The slave unit provides, to the master, the
following information.
Limit switch activation:
During opening or closing
movements, the master unit waits for the slave to end its
cycle. (Limit switch engaged).
Entrapment device activation: When the slave unit
detects an entrapment, the movement reverses both
operators.
Each terminal on the card along with the common
terminal (labeled -) provides a contact with a maximum
rating of 1 amp for a 30VDC accessory, each contact
closes under a certain condition of the gate leaf. Use the
following chart to achieve the desired activation.
Pin 1 Gate closed
Pin 2 Opening
Pin 3 Open (No limit switch engaged)
Pin 4 Opened
Pin 5 Pause Time
Pin 6 Fail Safe
Pin 7 Closing
Pin 8 Power failure and gate stopped
(Battery Use)
Pin - Contact Common

Note:
Apply the jumper wire between terminals two and
five when using “A” mode only.
