ESD
Many modern electronic components are susceptible to damage from Electro Static Discharge (Static Electricity).
During commissioning, avoid unnecessary contact with electronic components on PCB’s.
PCB’s which are Static Sensitive should be stored in anti-static packaging until installed.
Installation
General:
See “Safety” information above.
For connections, see Connection Details table above. Route control wiring separately from AC mains wiring.
Remove enclosure knock-outs as required to fit cable glands, taking care not to damage the PCB. Cable entry at
enclosure end is recommended.
Tools:
A 2.5mm flat screwdriver is recommended for the screw terminal block clamps and Variable Resistor adjustment.
A voltmeter is required during commissioning.
230VAC Supply:
Controller connection to 230VAC supply must be fused to 13A maximum.
The supply for single phase fans up to 13A total load may be connected via this control PCB, connect Fans to
230VAC output and Earth output terminals. For higher currents or 3-phase fans route supply direct to fans.
Fans:
Connect fan supply, speed control and tachometer leads, see table above for connections. If fan has a 10V
output wire cut back & insulate. If fans are Alarm Relay type (not Tachometer), connect Fan N/C & COM between
tachometer Input and 0V. If fan monitoring is not required, then link tachometer Input to 0V to prevent alarms.
Select Inputs:
Connect Run/Stop and Speed/Set-point select inputs as required for the application, see Tables below.
PC Switches and Variable Resistors:
Set DIP Switches and Variable Resistors as required, see tables and procedures below.
