Table 4-1 External Input Functions

This is the default setting on IN1
Stops UPS inverter from remote location. Use momentary (0.5 to 4 sec.) switches only.
This is the default setting on IN2
Driven by any customer-provided NO (Normally Open) dry contact. Closing the contact limits
the input current to a value (10-150% of the UPS's rated input) set in the TEST MENU
– "Power Demand Level 1" by an Authorized Toshiba Service Provider. Used to lessen the
inrush current experienced by the source, especially generators. Opening the contact returns
the UPS to its normal operation parameters.
This is the default setting on IN4.
Driven by any customer-provided NO (Normally Open) dry contact. Closing the contact limits
the input current to a value (10-150% of the UPS's rated input) set in the TEST MENU
– "Power Demand Level 2" by an Authorized Toshiba Service Provider. Opening the contact
returns the UPS to its normal operation parameters.
Annunciates "UF158 BATTERY LIQUID LOW", and is used with an electrolyte level sensor in
a wet cell battery system.
Driven by any customer-provided NO (Normally Open) dry contact thermal detection device
installed in the UPS's Battery Cabinet(s). When the contact closes, the UPS decreases its
battery charging maximum limit to 95% of the set charging voltage. If the contacts stay
closed (the battery temp is still abnormal) for two hours, the UPS will shut off its battery
charger. (Battery operation will still possible)
This is the default setting on IN3
Inhibits transfer to bypass.
Inverter operates in free run mode. (In other words, inverter does not track bypass as sync
source.)
Inverter will sync to an external source. For use with External Sync packages.
Starts all UPS inverters in an MMS system from a remote location.
Stops all UPS inverters in an MMS system from a remote location.
Inverter voltage is adjusted to match bypass voltage.
Use battery charge rate 2. This level is set in the TEST MENU by an Authorized Toshiba
Service Provider.
Battery charger will be stopped.
Annunciates "UA890 EXTERNAL ALARM".
Provides for another aux battery breaker (CB2) contact, similar in function to the standard
battery aux contact.
Energy storage device error signal. Mainly used with flywheels to annunciate recharge fault.
Stops the rectifier converter remotely.
For use with the internal Wave Capture tool; for use by Authorized Toshiba Service Providers.
