Power Options
The Con TROLL PROis available with 2 power options.
l
DC-powered, which requires a 9-36 VDC supply as the primary power source. This model can trigger low-voltage
(<50 V) relays only. See "Input/Output Connections" on page 24
l
AC-powered, which requires a 100-240 VAC as the primary power source. This model can trigger low-voltage
relays (<50 V) through the I/O board only (See "Input/Output Connections" on page 24), and high-voltage relays
(>50 V) through the AC board only.
Electro-Static Discharge (ESD) Recommendations
Before making wiring connections, discharge any static electricity from your body before touching circuit boards and
other internal components by touching a grounded metal object.
When making wiring connections, make sure to remain properly grounded by wearing an ESD wrist strap or similar
device.
Customer-Supplied Electrical Equipment
The end user must supply the following items.
l
18-12 AWG wire for electrical connections using conduit or 100-240 VAC power supply
l
24-12 AWG cable for connecting relays and PLC devices
l
For hard-wired locations using conduit, a 100-240 VAC or 9-36 VDC source with over current/disconnect protection
will be provided by the end user.
l
For cord-connected plug and socket locations, approved suitable wiring to be provided by the end user.
Ensuring Dome Connectors are Water-Tight
The dome connectors that you installed must be tightened securely after sensor cable or electrical cables are routed through
them.
These dome connectors are not meant to be weight-bearing.
For best results, ensure that the following conditions are met.
l
The cable does not slide or move after the connectors are tightened.
l
Sufficient cable has been threaded through the connector so that secure wiring connections can be made.
l
There is no weight or force from the water pulling on the cable.
Ensuring Good Electrical Connections
To ensure that all sensors and power sources function properly consider the following recommendations.
