SEQ/SEQ-1U User Manual
Software Version 2.0
5.2 Over-Ride Control
The SEQ has an optional over-ride and four menu items that control this function. If you do not require an over-
ride, you can skip the next four menu items since units are shipped with this function disabled. The over-ride can
be used for such purposes as fire safety over-ride, and can be set to either force the unit on or force it off when
an over-ride signal occurs. The over-ride input is also used for feedback when two or more SEQs are cascaded
together. This is covered in the applications section.
Menu Item Options Description
Over-Ride Input Contact Closure Use with relay contacts or latching switch
5 – 30V DC Use with an applied DC voltage of 5 to 30 Volts
Over-Ride Func Disable Disable over-ride if not required
Force On Force unit On when over-ride is applied to input
Force Off Force unit Off when over-ride is applied to input
Master Use when unit is the master in a cascaded chain
Pass-Thru Use when unit is an intermediate unit in a chain
Over-Ride Option Use Main Delays The main delays are used when an over-ride occurs
Special Delay The special delay is used when an over-ride occurs. A special
delay should not be used when the Aux Relay is used to provide a
fourth sequenced bank, as the sequencing between the fourth
bank and the three main banks during an over-ride may not
coordinate correctly.
Over-Ride Delay 0 – 30 Seconds Set delay time to be used only during an over-ride
5.3 Front Panel Push Button
The front panel push button allows the unit to be powered up or powered down from the front panel. There is one
menu item associated with the push button which allows it to be disabled or to operate only after a one second
delay. The delay option prevents the unit inadvertently powering on or off if the push button is accidentally
bumped. Note that the push button cannot be used in conjunction with applied voltage or latching type remote
control inputs.
