MECHANICAL LOADS must not be replaced with a taller handle otherwise the increased load applied to the joystick may result in permanentdamage. Penny+Giles joystick controllers are robust and designed to suit typical applications. System designers should ensure that the
joystick is not positioned where it could be subjected to excessive loads greater than the maximum allowable load stated in the
product specification. MODIFICATION AND USAGE Any modification of a joystick by the user is strongly discouraged and will invalidate the warranty and Penny+Giles liability.
The handles supplied with the finger operated controllers are intended for fingertip and not full hand operation. Handles USER MAINTENANCE/ADJUSTMENT All joysticks are supplied by Penny+Giles fully adjusted and ready for installation. There are no user adjustable or
maintainable parts within the joysticks. Any attempt to dismantle the joystick will invalidate the warranty and may leave the
system into which the joystick is installed in a dangerous condition. SAFETY For a system to operate safely it must be able to differentiate between commanded and uncommanded inputs. System
designers should take steps to detect and manage joystick and system failures that may give rise to an erroneous output. Forsafety critical functions we recommend that an independent momentary action system enable’ switch is used. This switch canbe incorporated into the joystick as a Person Present’ switch or can be a separate foot or hand operated momentary switch.
All functions controlled by the joystick should be disabled when this switch is released. The control system should look for theappropriate system enable’ switch output before the joystick is displaced from the neutral position. Functions controlled by thejoystick should not be enabled until this is the case. JOYSTICK INTEGRITY CHECK ON POWER UP On system power-up, the system should check that all joystick outputs are in neutral and safety critical functions controlled bythe joystick should not be enabled until this is the case. LIFE Penny+Giles joysticks are designed and tested to provide a working life that is acceptable for the majority of applications.
System designers should be satisfied that the life stated in the joystick specification is sufficient for the intended application.
JC2000 INSTALLATION AND APPLICATION NOTES
SEALING THE JOYSTICK TO THE PANEL See panel mounting detail on page 23 for recommended machining detail to accept the JC2000. Prior to installation checkthat the gate (lever movement limiter) positioned under the gaiter at the top of the joystick is correctly located and orientated.The joystick is sealed above the mounting surface to prevent dust and water ingress to IP65 and is supplied with mountinghardware (sealing gasket and trim plate) suitable for mounting from above the panel face. The effectiveness of the
industrial seal is
dependent on the mounting surface being sufficiently rigid to compress the sealing gasket. The finish of the mounting surface
is critical to achieving an adequate seal and rough surface finishes, paint chips, deep scratches etc. should be avoided. The
joystick should not be used if the flexible rubber gaiter becomes perforated. Below the mounting surface the joystick should be allowed to breathe freely but be protected from excessive dust and directwater spray. Where the joystick is mounted in a control box, the box should be allowed to breathe at its lowest point. If the boxis subjected to water spray it may be necessary to provide a waterproof breather at the lowest point.It is possible to mount the JC2000 from under the panel surface by discarding the trim plate and sealing gasket andcompressing the base of the flexible gaiter against the panel and mounting flange. This reduces the lever height above the
panel, but increases the space required to accommodate the joystick body below the panel. See panel mounting detail on
page 23 for dimensions.
