ESTOP Function
If an ESTOP switch is wired to the IB2-1 Controller Interface Board, customer-furnished system ground applied to terminal DI8+
activates the ESTOP function. The ESTOP function shuts down and locks out the rectifiers and solar converters, shuts down and
locks out the optional -48 VDC to +24 VDC converters or optional -48 VDC to -58 VDC converters, shuts down and locks out the
inverters (if equipped with optional inverter system), and opens the optional low voltage disconnect (LVD) contactors (battery and
load type). If the system has battery connected and does not contain a battery LVD or the controller power option is set to Battery
Pwr (jumper J4 on the system interface board is set to Battery Pwr), the controller will remain operational. If the system does not
contain battery or load LVD(s) and has battery connected, the loads will be sustained by the battery voltage.
For Systems NOT Containing a Battery LVD: When the ESTOP signal is removed, LVD contactors (load type) will close after the “LVD
Reconnect Delay” has elapsed (customer configurable via the controller) if battery voltage is present on the bus. Rectifiers, solar
converters, optional -48 VDC to +24 VDC converters or optional -48 VDC to -58 VDC converters, and inverters (if equipped with
optional inverter system) will remain off. The rectifiers, solar converters, and inverters (if equipped with optional inverter system) will
restart when the input power to these is removed and restored after 30 seconds or more (until the LEDs on the modules extinguish).
To restart the -48 VDC to +24 VDC converters or -48 VDC to -58 VDC converters: remove the converter, wait 30 seconds or more
(until the LEDs on the converter extinguish), then re-insert the converter.
For Systems Containing a Battery LVD: When the ESTOP signal is removed, LVD contactors (battery and load type) will remain open.
Rectifiers, solar converters, optional -48 VDC to +24 VDC converters or optional -48 VDC to -58 VDC converters, and inverters (if
equipped with optional inverter system) will remain off. The rectifiers and solar converters will restart when the input power to these
is removed and restored after 30 seconds or more (until the LEDs on the modules extinguish). When the rectifiers restart, LVD
contactors (battery and load type) will close after the “LVD Reconnect Delay” has elapsed (customer configurable via the controller)
and the -48 VDC to +24 VDC converters or -48 VDC to -58 VDC converters, and inverters (if equipped with optional inverter system)
will restart.
NOTE!
If a customer-furnished method to disconnect the input power to the system is not provided, the rectifiers will stay
locked OFF until the input power is recycled. If the ESTOP signal is removed without recycling the input power, the rectifiers
will remain off and have a local alarm visible on the module. The ESTOP alarm from the controller will extinguish. The
controller will not issue an alarm for this condition.
External Battery Disconnect Circuit Breaker Alarm Input
Connect the alarm lead from an optional external battery disconnect unit or the battery disconnect circuit breaker on an optional
battery tray to the negative (–) side of Digital Input #3 (terminal 5 of connector J3). -48VDC is applied to the alarm lead when the
circuit breaker is in the OFF position. Refer to Figure 5.22.
Programmable Relay Outputs
The IB2 provides eight (8) programmable alarm relays with dry Form-C contacts. Connect up to eight (8) relay outputs to the IB2.
Refer to Figure 5.21 for terminal locations and Table 5.4 for pin-out information.
Refer to the NCU Instructions (UM1M830BNA) for programming information.
Relay Ratings: Refer to the following.
a) Steady State: 0.5 A @ 60V DC; 1.0 A @ 30V DC.
b) Peak: 3 A @ 30V DC.
The relays may be preprogrammed for specific functions. Refer to the configuration drawing (C-drawing) supplied with your system
for your system’s specific configuration.
