Configuration and Operation Manual
button will skip over the LOSS OF COMMAND mode when the unit is configured for a 0-5V or 0-10V
command signal (see COMMAND TYPE). When the OVERRIDE mode is enabled (see OVERRIDE MODE),
the MODE button is disabled and the Manual/Pot Cal indicator will turn on steady.
ADJUST UP
and ADJUST DOWN
(▲)
The adjust up (▲) and adjust down (▼) buttons are used to adjust the setting of any given function.
When a function is selected by the MODE button, the adjust buttons will affect that function only. Note,
that the AUTO mode does not have any adjustable settings, and therefore, the adjust up (▲) and adjust
down (▼) buttons have no effect. Also, the adjust buttons are disabled in the OVERRIDE mode.
OVERRIDE MODE
The OVERRIDE mode is not selected by the MODE button and can be enabled at anytime by connecting
a resistance greater than 250 ohms to the Override Input (J7 pin 1 and pin 2). While the OVERRIDE
mode is enabled, the MODE button and adjust buttons are disabled, and the Manual/Pot Cal indicator will
turn on steady to indicate that the unit is being controlled by the Override Input. Shorting J7 pin 1 to pin
2 returns the unit to normal operation and the previously selected mode. Note that earlier models may
not have connector J7, and therefore do not have the OVERRIDE mode feature. Controlling the FDHC-
100 from the Override Input is accomplished by connecting a specific resistance to select a specific
operation. The table below defines the operations and their associated resistance. See Special
Applications for details on using the Override Input for an Auto/Manual Station.
RESISTANCE
> 4.3K ohms
3.3K ohms ±5% LATCH
2K ohms ±5%
1.2K ohms ±5% CLOSE
510 ohms ±5%
The OPEN function will operate the motor in the
CLOSE function operates the motor in the
function will maintain the previously selected function; this allows momentary switches to be used for the
OPEN and CLOSE functions. The OFF and STOP functions turn the motor off, which also unlatches the
OPEN or CLOSE functions.
Note that the OPEN and CLOSE functions may work in reverse until the
by the OPEN and CLOSE modes. The FDHC-100 will automatically turn the motor off when the
closed
positions are reached. However, if a feedback fault occurs (see FAULT INDICATOR), the motor
will be turned on for a period of 15 minutes in the selected direction. For this reason, limit switches
should be used when using the OVERRIDE mode, and should be set to a position acceptable for the
application. The 15 minute period can also be terminated using the OFF or STOP function.
The motor is also automatically turned off if the FDHC-100 detects a stall (see STALL DETECTION). An
OPEN or CLOSE operation can be attempted again after switching to the OFF, LATCH, or STOP functions
first.
