Ransburg PulseTrack2 A11515-XXXXX - Manual (Page 25)

Enable Inputs
Discreet enable inputs are available for rotators
1 through 6 to interlock the speed control with a
remote signal. This can be done pneumatically
(as described previously under Pneumatic Con-
nections) or electrically. The electrical inputs for
each rotator are available at breakout terminals
J3-C15 through J3-C20. These inputs are active
low. Thus, when they are connected to ground,
speed control is enabled.
Master Enable Input
A master enable switch exists on the front of the
control panel that must be enabled for any rotator
speed control to be active. If it is disabled, all rotator
speed controls are inactive. This is convenient if it
is desired to turn off all rotators at the same time.
This active low signal is also available remotely
at breakout terminal J3-C14. Thus, this discreet
input can be made active by connecting J3-C14
to ground via a remote switch or PLC contact.
Master Reset Input
A master reset switch exists on the front panel
for the purpose of resetting any faults that may
occur. This momentary active low signal is also
available remotely at breakout terminal J3-C13.
Thus, this discreet input can be made active by
connecting J3-C13 to ground via a remote switch
or PLC contact.
Temperature Inputs
Analog temperature inputs (4-20mA) for up to 5
probes are available at breakout terminals J2-A3
through J2-A6 and J4-B1. Signals supplied to
these inputs from remote mounted temperature/
humidity probes (optional) are processed by the
main control board and sent to the corresponding
Temperature/Humidity Card (optional) for display.
Terminals J2-A3 through J2-A6 are dual function
terminals. They may be used for analog speed
setpoint input or temperature input depending
on the configuration of the PulseTrack 2 system.
Humidity Inputs
Analog humidity inputs (4-20mA) for up to 5 probes
are available at breakout terminals J4-B2
through J4-B6. Signals supplied to these inputs
from remote mounted temperature/humidity
probes (optional) are processed by the main control
board and sent to the corresponding Temperature/
Humidity Card (optional) for display.
Outputs
Analog Speed Outputs
Analog speed output signals are available for
rotators 1 through 6 at breakout terminals J2-
A13 through J2-A18. These outputs can all be
set so that 0-10VDC or 4-20 mA represents 0 to
100,000 rpm using jumpers E1 through E6 and
dipswitch SW1-7 on the Control Card (see Figure
10). The jumpers and dipswitch are factory set to
the 0-10VDC positions. Table 4 summarizes the
analog output settings.
Rotator Fault Outputs
Discreet fault outputs are available for rotators 1
through 6 at breakout terminals J2-A19 through
J2-A24 to indicate remotely which rotator caused
a fault condition. These active high outputs put
out 24VDC when active. Maximum output current
from each output is 250mA.
Run Outputs
Discreet run outputs are available for rotators 1
through 6 at breakout terminals J2-A25 through
J2-A30 to indicate remotely when speed control
is enabled for a given rotator. These active high
outputs put out 24VDC when active. Maximum
output current from each output is 250mA.
Master LOF Output
A 24VDC discreet output exists at breakout terminal
J3-C21 to indicate when a loss of feedback (LOF)
fault occurs on any rotator. Using this output in
conjunction with the individual rotator fault output it
is possible to remotely determine on which rotator
the LOF fault occurred. Maximum output current
from this output is 250mA.
Master Underspeed Output
A 24VDC discreet output exists at breakout termi-
nal J3-C22 to indicate when an underspeed fault
occurs on any rotator. Using this active high output
in conjunction with the individual rotator fault out-
put it is possible to remotely determine on which
rotator the underspeed fault occurred. Maximum
output current from this output is 250 mA.
