1. Overview
Congratulations on selecting a Nice gate
operator for automating your gate system. With
proper selection, system design, installation and
maintenance this operator should provide years
of reliable operation.
This manual covers the following Nice operator
models: 3501 with 1050 (see 1551 manual for 1050
board programming and controls available).
1.1 1050 Control Board
The 1050 main control board is housed in a
protective plastic enclosure that includes a 2-line
LCD, with 5 dedicated buttons and 3 buttons
for navigation of the setup, programming, and
information menus, as well as 3 buttons for open,
close, and stop. Connectors for power, inputs,
and output peripherals are arranged around the
edges of the board and clearly labeled. A plug-
in connector is provided for direct installation of
a Nice-brand receiver which can be controlled
by up to 1000 transmitters. A recessed RJ-11
jack offers a connection to an optional O-View
programmer and optional Bluetooth module that
can be programmed via PC. Connectors for other
Nice-brand plug in accessories include 2-wire
Bluebus, self-monitored photocells for entrapment
protection. Dry contact inputs are provided for
loop, probe, and photoelectric detectors, as
well as guard station and fi re department control
of gate opening and closing. Voltage outputs
(+12VDC and +24VDC) are also made available
to power safety and entrapment-prevention
devices, and a magnetic lock if required. On
board charge control circuitry delivers reliable
power to a backup battery (if installed) and the
unit is equipped with input for a solar panel for
self-powered installations.
The 1050 main control board accepts DC input
voltage ranging from 10VDC to 32VDC. A 2-line
LCD with dedicated buttons allows installer to
quickly program the 1050 when changes to its
factory-default settings need to be made. A real
time clock/calendar enables programming for
scheduled weekly or daily events like opening,
closing, or locking the gate. Gate opening and
closing speed, acceleration, soft-start settings,
and reversing speed may be set to factory
default settings, or individually programmed per
customized gate installation requirements. Built-
in current sensing enables inherent gate force
monitoring and limiting for safety and an on board
alarm indicates when two sequential obstructions
have been sensed in either direction. The “Learn”
function helps gate installer confi gure Nice 1050
control board semi-automatically for optimum
settings of gate opening and closing speeds,
with simple programmable adjustments to force
and speed settings that may be made with the
programming button on the control panel.
