LOGIC CONTROLLER
The logic controller contains three 8-position DIP switch
assemblies that are used for:
— Serial port configuration
— Communication parameters
— Setting the LON/SLC address.
S5 — Hardware Serial Port Configuration
Verify that S5 switches are set as follows:
1 — Closed
2 — Open
3 — Open
4 — Closed
5 — Open
6 — Open
7 — Closed
8 — Open.
S6 — Diagnostic Serial Port Configuration
Diagnostic serial port is
intended for factory use only.
Switch settings will not affect
normal operation.
S7 — LON/SLC Address
Set switches for the LON/SLC
address. Valid addresses are
from 5 to 247, and must be an
odd number. If an address
outside this range is selected,
the address will default to 5.
S7-1 = LSB, S7-8 = MSB.
ISOLATION MODULE
A slide switch (SW1), located on the top edge of the
module, controls the 24 volt ground fault monitor
function.
On = Enabled
Off = Disabled
Determine the type of LCU being used (Refer to the
label on the LCU mounting cage.) Set SW1 as follows:
Off — EQ2100LCU
On — EQ2101LCU
LON/SLC DEVICE ADDRESS SWITCH
SETTING
Each individual device on the LON/SLC must be
assigned a unique address. Addresses 1 to 4 are
reserved for gateway use. Address 1 is for the main
gateway. Valid addresses for field devices are from 5 to
250. If the address is set to zero or an address above
250, the communication module will ignore the switch
setting. Duplicated addresses are not automatically
detected. All modules with the same address will report
on that address. The status word will show the latest
update, which could be from any of the reporting
modules at that address.
NOTE
Logic controllers utilize two consecutive LON/SLC
addresses, the first of which must be an odd
number, i. e. a Logic Controller with an address of
7 will occupy both 7 and 8 on the LON/SLC.
Selection of the node address for field devices is
accomplished by setting rocker switches on a DIP
switch assembly. (Note that only the first eight of the 12
switches are used for selecting the address.) The
address number is binary encoded with rocker switch
No. 1 on the 8 position switch assembly being the LSB
(least significant bit). Each rocker switch has a specific
binary value, as shown in Figure VIII-3. The node
address is equal to the added value of all closed rocker
switches. All open switches are ignored. For example:
for node No. 5, close rocker switches 1 and 3 (binary
values 1 + 4); for node No. 25, close rocker switches 1,
4 and 5 (binary values 1 + 8 + 16).
Power must be cycled before the new address will take
effect.
For your convenience in setting the address switches,
refer to the table “Address Switch Settings” at the back
of this manual.
After setting the address switches, record the address
number and device type on the “Address Identification
Chart” provided with this manual. Post the chart in a
convenient location near the LCU.
