Getting Started
Q. My module will occasionally fail when I power up my system. Why does this happen?
A.
Normally this is caused by an inadequate power supply corrupting the memory.
When determining the size of a power supply be sure to include ALL sources of
energy consumption and also account for the surge these devices require. For
example an OP--613 requires 1.5 Amps (for 2 milliseconds) at start-up, but after
start-up needs only 90 mA at 24VDC to function.
Q. My panel lights flash when connected to the bottom port of a D2--240. What’s wrong?
A.
The lower port on the D2--240 defaults to ASCII mode and needs to be set to HEX
mode in order to communicate with an Optimate panel. Access the port settings from
DirectSOFT by PLC-->Setup-->Setup Secondary Com Port.
Q. In a multi--panel system, how should I wire the panels if more than one power supply is being
used?
A.
It is highly recommended that all the power supply grounds be wired together.
Failure to do so may result in failed modules. Also, ensure that power supply and
wire size is large enough to handle the current, especially at long distances. It is also
highly recommended that all shields be tied to earth ground. For power cable
distances greater than 50’ or in noisy environments, a two-twisted pair shielded wire
such as Belden 9729 (or equivalent) should be used. There is an OP--9001
Supplemental Sheet with diagrams, included with all OP--9001’s, depicting the three
most typical wiring arrangements.
Q. Why does my module work in a stand-alone situation, but not when connected to my
OP--9001?
A.
The most obvious reason is that the module was not configured for a multi-panel
situation or that the OP--9001 was not configured for the module. Next, the OP--9001
communicates with the module via RS--422 cable, so verify that the pin-outs are
correct. Lastly, the RS--422 driver in the module or OP--9001 may have failed due to
cabling or power supply problems. Please reference the OP--9001 Supplemental
Sheet for wiring directions.
Q. I’ve loaded a new configuration into my panel and still get some of the old messages. How do I
get rid of the old messages?
A.
The OP--WINEDIT does not clear the message list in the OP panel when you load
a new configuration. If you had more messages in the old configuration than the new
configuration, the extra messages do not get overwritten. You can clear the
message list from CONFIGURE>CLEAR LIST>THE CONNECTED PANEL. Reload
the new configuration and the old messages will be gone.
