ASTAT-XT RVSS PANEL

2. Customer Terminal Board – “CTB”

Inside the panel enclosure there are terminal boards for customer connections. The wiring diagram
provides a reference of the terminal board connection and refer the ASTAT-XT users guide for details on
each of the functionality and programming, the brief descriptions are as follows:













CTB1-1

Wire this Dual Set / Reverse / Reset Input This terminal allows for
activating the Dual Adjustment / Reversing / Reset Contact functionality on
the ASTAT-XT 8 as required








CTB1-2

External Fault Input. Wire this for External Fault Input on ASTAT-XT as
required.
When the input from a N.O. contact that is connected between terminals
is closed, the ASTAT-XT will trip 2 seconds after the contact closes


CTB1-3
through CTB1-5

Thermistor Input. Thermistor input is programmable as a PTC or NTC
type thermistor. The trip value is adjustable between 1-10Kohm, preset
delay of 2 Sec. Connect thermistor and/or Analog output shield to ground
Terminal. User programmable Analog output (0-10VDC or 0-20mA or 4-
20mA)

CTB1-6 and CTB1-7

Analog Output. User Programmable Analog output (0 - 10V DC or 0 -
20mA or 4-20mA)


CTB1-8, CTB1-9, CTB1-10

Customer Safety Interlocks Input. Put normally closed contacts between

and CTB-19 CTB1-8 and CTB1-9 and between CTB1-10 and CTB1-19. An

open circuit between these positions will cause the Soft Starter to drop
out resulting in power being removed from the motor. These positions
come jumpered together from the factory and require removal of the
factory jumpers prior to connecting customer normally closed contacts.






WARNING: When the circuit breaker/disconnect handle is turned

to the “On” position, terminal board points can be at 115 VAC with
respect to ground. Therefore, prior to making any connections to these
points lock the disconnect handle in the “Off” position. In fact, good
safety practice dictates that prior to servicing any electrical equipment
that all sources of electrical energy be disconnected and “locked out” to
avoid reconnection by a third party unaware of the maintenance efforts
underway.

WARNING: Do not use this for phase rotation correction and ensure

application support the reverse rotation before using this functionality
