INSTALLATION
GENERAL

MECHANICAL

The Precision may be supplied as PCB only, in 316 stainless steel IP65 (Nema 4) enclosures, or in painted steel IP65 (Nema 4)
enclosures.
General.
Install Precision in areas of minimal vibration.
•
Install in an area free from high electrical noise or interference.
•
Install in an area where there is low risk of impact to the Precision.
•
The Precision will operate in ambient temperatures of 70°C (158°F). At temperatures higher than this the display may become
•
difficult to read and the high temperature alarm will activate. Cooling should be provided if the Precision is to be installed in
conditions with ambient temperatures of 70°C (158°F) or higher.
P2.Enhanced.Demand.Mode.
Ensure pneumatic sensing lines are kept as short as possible to minimise pressure losses.
•
Ensure pneumatic sensing lines are free from blockages, kinks or leaks.
•
Installations.where.PCB.only.has.been.supplied.
Ensure that installation is made into enclosures chosen with due consideration of the nature of the location, and that the
•
boards are protected from moisture, heat above 70°C (158°F), dust, and chemical attack.
Ensure a common earth connection is present for all conductive material within immediate proximity to the device being
•
powered, e.g. a common earth connection between the baseboard and mounting bracket, enclosure, etc. Please follow all
local electrical standards.

ELECTRICAL INSTALLATION

Warnings:.
Electrical installation to be undertaken by suitably qualified technicians.
•
Ensure that mains power has been isolated before conducting any work on the Precision.
•
Connecting.power.to.the.Precision.
Applying power to the AC/DC and AC/AC Precision motherboard (AC Voltage models):
Ensure input voltage is 110 or 240 V AC (+/− 10%), 50/60 Hz.
•
Ensure power supply is not affected by high load or noisy electrical machinery such as fans, which may cause unreliable
•
system operation.
Connect Earth, Active and Neutral supply to their respective terminals (ref. Figures 2 and 5, item 10).
•
Applying power to the DC/DC Precision motherboard (DC Voltage models):
Ensure input voltage is 24 to 48 V DC (+/− 10%).
•
Ensure power supply is not affected by high load or noisy electrical machinery such as fans, which may cause unreliable
•
system operation.
Connect Earth, Positive and Negative supply to their respective terminals (ref. Figure 2, item 10).
•
Surge.Protection.and.Earthing.
Goyen Controls recommends the use of a Metal Oxide Varistor (MOV)-based surge protection device between the supply
•
voltage and the Precision. Clamping voltage = 275 V RMS (approx.), Energy Absorption = 175 joules (approx.).
Ensure that when using a metal enclosure, both lid and box are connected to the supply earth.
•
Connection.of.solenoid.valves.and.expansion.cards.to.Precision.outputs.
Please refer to the system wiring diagrams (Figures 8–11) on pages 8–11.
