8.3.4. Fault Input
The C1000 series controller has a single fault input that is used to activate UCB Fault Input 2 in
each microturbine bay. Refer to the C1000S/C800S/C600S Technical Reference (Table 1) for a
detailed description of the internal wiring and operation of the fault input.
8.3.4.1. Fault Input Settings
Refer to the CRMS Maintenance Edition Technical Reference (Table 1) and make the following
settings for fault inputs:
Enable/Disable (On/Off) – If On, control detects a fault input to the system from an
external fault source.
Fault Level defines the system severity level of this fault source.
o Level 2 – Warning issued. Microturbine will continue to operate.
o Level 3 – Standard microturbine shutdown sequence (cooldown).
o Level 4 – Fast microturbine shutdown sequence (warmdown).
Time (sec) – adjustable debounce time for fault input detection from an external device,
i.e., how much time the fault is detected for before the fault is latched in the system.
Active (Open / Close)
o Active Open – If the fault input contact changes state from a closed position to an
open position the fault is declared.
o Active Close – If the fault input contact changes state from an open position to a
closed position the fault is declared.
Fault input 1 is used to shut down the microturbines in the event that the external fault
device (normally closed) is activated. This is change of state at relay R1 contacts is
configured as Active Close in CRMS.
Fault input 2 is used to shut down the microturbine in the event that the contact
(normally open) is activated. This change of state is configured as Active Close in
CRMS.
8.4. External Controller Connections
A Capstone Logic Controller (CLC) is used to connect multiple C1000S/C800S/C600S
microturbines into a MultiPac, which can also include C200 microturbines. A CLC can also be
connected to an individual microturbine when the customer application requires a remote control
panel, custom graphics, or other features of the CLC. When connecting to a CLC, the C1000
series controller panel PC is disabled, and the CLC communicates directly to each C200
microturbine module within each microturbine. The CLC then becomes the MultiPac master and
provides a single point of control for each individual microturbine module or separate C200
microturbine. The C1000S/C800S/C600S microturbines are pre-wired to simplify connection to a
CLC, as described below (Figure 64).
