PRSU Series, Operating Instructions Manual (Revision 1.0)
Device Startup Verification (PRSU/2)
Before creating any electrical connection to the device´s relay channels, RESET circuit, or
switch monitoring terminals, select a power supply with appropriate voltage settings and ensure
its output is set OFF.
Connect the power supply output (with appropriate input power source; see requirements listed
on Pages 13 and 14 of this manual) to the PRSU/2 power input terminals (A1, A2), then apply
the correct voltage for the device and verify that the “Power” LED illuminates.
Turn OFF power from the supply and make the appropriate connections to the switch monitoring
channels, relays and RESET circuit according to the configuration guidelines laid out on Pages
8 through 10 of this manual.
When the correct configuration is implemented and power is again applied, monitoring of the
switches/sensors will only occur once a RESET signal is received by bridging S33 and S34 with
an appropriately rated wire. See pages 8 through 10 of this manual for more information.
After the RESET signal is received and the monitored switch is in the unactuated state, the relay
contacts (13
→
14), (23
→
24) will close.
Device Startup Verification (PRSU/4, PRSU/5)
Before creating any electrical connection to the device´s relay channels, RESET circuit, or
switch monitoring terminals, select a power supply with appropriate voltage settings and ensure
its output is set OFF.
Connect the power supply output (with appropriate input power source; see requirements listed
on Pages 13 and 14 of this manual) to the PRSU/4 or PRSU/5 power input terminals (A1, A2),
then apply the correct voltage for the device and verify that the “Power” LED illuminates.
Turn OFF power from the supply and make the appropriate connections to the switch monitoring
channels, relays and RESET circuit according to the configuration guidelines laid out on Pages
8 through 10 of this manual.
When the correct configuration is implemented and power is again applied, monitoring of the
switches/sensors will only occur once a RESET signal is received by bridging S33 and S34 with
an appropriately rated wire. See Pages 9 through 10 of this manual for more information.
After the RESET signal is received and the monitored switch is in the unactuated state, the relay
contacts (13
→
14), (23
→
24) and (33
→
34) will close. Contacts (41
→
42) will open.
