FIGURE 5—Operation Display & Additional Programming Options
When the unit is operating, the display will indicate which output is active for the duration of its
programmed time delay. For relay output #1, a
1
will be displayed and
2
will be displayed for relay output
#2. If the delays d3 or d4 are used (such as an installation using a Mag Lock or a Vestibule application),
the delay will be evident between the displaying of both outputs.
In addition to the settings already described in the previous sections, below is a listing of various options
which are programmable on the TDM. The LED display vs. function are as follows:
––
= Ready Mode (flashing)
d1
= Time Delay or "ON TIME" of relay output #1—0.0 to 99 seconds
d2
= Time Delay or "ON TIME" of relay output #2—0.0 to 99 seconds
d3
= Time Delay between d1 and d2—0.0 to 99 seconds
d4
= Time Delay between d2 and d1—0.0 to 99 seconds
i1
= Switch Input #1—(N.O. or N.C.)
i2
= Switch Input #2—(N.O. or N.C.)
i3
= Switch Input #3—(N.O. or N.C.)
i4
= Switch Input #4—(N.O. or N.C.)
o1
= Relay Output #1—(N.O. or N.C.)
o2
= Relay Output #2—(N.O. or N.C.)
- -
= Error (flashing)
The
PUSHBUTTON FAULT INDICATOR
is a special feature designed to alert the installer if a pushbutton is
"stuck" in the active position or if the wires have shorted. If this occurs, the display will flash double dots
(
.
.
). Additionally, this could mean that the wiring did not match the programmed parameter. In other
words, the unit may be programmed for use with a normally open switch, but may be wired to a normally
closed switch. Normal operation will resume once the fault condition has been cleared.
WET/DRY CONTACT OPTION:
The TDM has the option of supplying power to relay output #1 contacts. This is known as "WET" contacts
instead of the conventional "DRY" contacts or simple contact closure. Providing this voltage can simplify
the wiring of installations where an Electric Locking device is used. However, the voltage supplied to the
output is the same voltage supplied to the input of the TDM and must be compatible with the Locking
device to be controlled. Please contact the factory for additional information.
