3. Technical Specifications
The ASTAT-CD Plus functions such as soft stop, kick start, etc., can be enabled (ON) or disabled (OFF) in their dedicated parameters by using the keypad.
Most of these functions can be enabled or disabled remotely as well, through the programmable inputs I3 or I4 (terminals 3-57 and 4-57).

Programmable Relay Outputs
The ASTAT-CD Plus includes three programmable relays 1r, 2r and 3r (dry contacts). ASTAT-CD Plus terminals are 11-12-14, 23-24 and 33-34
These relays can be assigned to several functions, as shown below.

More than one function can be enabled in the ASTAT-CD Plus, either by the keypad or through the programmable inputs I3 and I4, but there are some functions
which may not work as expected during stopping, such as when they are simultaneously enabled. When two or more of the below functions are simultaneously
enabled, the priority is defined in the following table:
DC Brake (B=ON) a b c
Linear Ramp (S, D=ON) a a a
Soft Stop (S=ON) b a c
Pump Control (S, C=ON) c a c
DC Brake (B=ON)
Linear Ramp (S, D=ON)
Soft Stop (S=ON)
Pump Control (S, C=ON)
a The unit stops by Linear Ramp
b The unit stops by DC brake after the Soft Stop is completed.
c The unit stops by Pump Control
