This input should be fed 24 vdc from the HPU controller whenever the HPU is
running. Unless this signal is received by the Kp-300, the Blocking Valve Output
will never turn on and the Show Cycle Counter will not advance.
To help keep shows from being run when the HPU has been started by its local
Hand/Off/Auto switch, the HPU Stopped Input and HPU Running Input signals are
often routed through the ʻAutoʼ position on the switch. If the switch isnʼt in the
ʻAutoʼ position, the HPU Stopped LED and HPU Running LED wonʼt light and the
Blocking valve wonʼt be enabled.
If there is no HPU in your application, or there is no ʻrunningʼ output from your
HPU, you can turn on DipSwitch #2. The ʻHPU Runningʼ LED will then light when-
ever the Kp-300 thinks that the HPU is not running.
3) Blocking Valve Output from Kp-300
A blocking valve is a secondary digital valve that blocks the normal servo
valves on a hydraulic motion base. These valves are always installed so that they
only allow the servos to operate the motion base when power is applied them.
Orifices (usually fixed) allow the oil to drain out of the cylinders so that gravity and/
or remaining accumulator pressure will lower the motion base when power is re-
moved. This so that if there is a power failure or any other error condition, the mo-
tion base will park itself safely. In most motion base applications, the power is re-
moved from the blocking valves during the Load/Unload times so that there is no
possibility of the motion base moving while riders are walking in and out.
This output is used to control the blocking valve attached to the motion base.
The output capacity of this output is 150 ma. at 24 vdc. Since the solenoid valves
used for blocking valves usually draw far more current than this, a solid state relay
will most likely be required on this output. If you are using one of Gilderflukeʼs
ʻElectronic Blocking Valvesʼ, you will not need to use a relay.
The blocking valve is programmed from the motion profile stored on the Smart
Brick System. Unless the Kp-300 is receiving an active HPU Running Input and
the Kp-300 is not in an E-Stop condition, the Blocking Valve Input from the Smart
Brick System will not be passed through to the Blocking Valve Output.
4) HPU Run Output from Kp-300
This output from the Kp-300 is turned on when the operator presses the HPU
Start Button or the motion profile in on the Smart Brick System has the Remote
HPU Start Input programmed active. This output can not be turned on if the Re-
mote HPU Stop Input from the Smart Brick System is active or there is an active
