3.2.74 PB2SW - PB2 Switch
PB2SW
is one of three general purpose switches
available in each loop. It can be utilized for switching
Boolean signals in such applications as: toggling the
EITS (External/Internal setpoint Transfer Switch)
function block, Start/Stop, controlling the position of a
TSW (Transfer Switch) function block for switching
analog signals, or other operator initiated actions.
The switch can be configured for momentary or
sustained operation. As momentary, the switch will
transfer to the NO position when the button is pressed
and will return when released. Momentary action is used
in toggle applications such as changing the function of
the EITS function block. In the sustained mode, the
switch will alternate positions each time the button is
pressed. An unconfigured NC input defaults to 0 and an
unconfigured NO input to 1. With firmware 1.30 and
higher, the button can be remotely activated through a
command over Modbus or LIL.
This block operates with an operator faceplate that includes green and red LEDs that are turned on using input MD.
A HI (1) input will turn on the Green LED and a LO the Red LED. The default connection will be the PS output of
the block but should be changed as required to display the correct status. The message parameters do not apply to
the current product.
POWER UP - When the switch is configured for
momentary action, it will always power up in the
NC position. For sustained action, with the
POWER UP parameter set to YES, the switch will
power up in the last position during a hot or warm
start, and during a cold start will power up in the
NC position. When the POWER UP parameter is
set to NO, the switch will power up in the last
position during a hot start. During a warm or cold
start, it will power up in the NC position.
