Equipment-Specific Safety Information
The following safety information is specic to the Nordson EFD Toµch controller.
Intended Use
• This equipment is for indoor use only.
• Use the Toµch controller only in conjunction with its associated power cable and, if needed, its associated
extension cable.
• Do not open the Toµch controller.
Unintended Fluid Release
• Prior to initial operation, check to see if uid ows out of a valve that is turned off even when no uid pressure
is being applied. If this occurs, it may be because the uid reservoir is positioned higher than the valve, in which
case hydrostatic pressure causes the uid to ow out of a valve that is not closed. Position the uid reservoir low
enough such that no uid leaks from the valve when the valve is shut off.
• In the case of damage to the piezo actuator or the Toµch controller, the valve may transition from a CLOSED to
an OPEN condition, which can cause uid release. Nordson EFD recommends continually monitoring the status
signal of the Toµch controller and immediately and automatically bleeding the uid reservoir if these signals
indicate an error.
• Before connecting or disconnecting a valve cable, release uid pressure and disconnect and lock out power to the
Toµch controller.
