Chapter 5: Keypad Menu Items and Parameters
5.4.12 – ‘Trips’ Menu
This menu holds all the parameters that are associated with control of the various trips
Trips
Range: 0 to 17 trip number Default: 0
The ‘Trips’ sub-menu accesses a trip history of the unit’s last five trips. These trips are recorded
automatically, and need no intervention from the user. They are useful in troubleshooting a unit.
Most trips can be turned off, either via this menu, or through the ‘Trip Byte’, P127, or via the
‘Current’ menu for the current related trips. Below is a list of each trip condition used by the
SR44.
Trip Numbers and Explanations:
• 01 ‘Phase Loss’ – One or more input phases are missing at start, during the ramp, and after full
voltage; even when running on bypass. (See section 5.4.5, Line Contactor.)
• 02 ‘Too Hot’ – Soft starter heat sink is too hot. (This trip applies only to units SR44-30 and larger.)
• 03 ‘Comms’ – Errors in serial communications while communications are still active between the
user interface and the Soft Starter.
• 04 ‘SCR Firing’ (Thyristor Sensing Trip Type C) – Short-circuit thyristor after full voltage.
• 05 ‘SCR Signal’ (Edge Sensing Trip) – Short-circuit thyristor during the ramp and after full voltage.
Motor-side phase loss during the ramp and after full voltage.
• 06 ‘SCR Signal’ (Sensing Trip Type A) – Short-circuit thyristor during the ramp and after full voltage.
Motor-side phase loss during the ramp and after full voltage. Input-side phase loss during the
ramp and after full voltage.
• 07 ‘Sensing Signal’ (Sensing Trip Type B) – Short-circuit thyristor or external noise during the ramp
and after full voltage. Motor-side phase loss during the ramp and after full voltage.
• 08 ‘SCR Loss Motor’ (Motor-Side Thyristor Loss) – Short-circuit thyristor at the start. Motor-side phase
loss at the start.
• 09 ‘Sensing Signal’ (Thyristor Sensing Trip Type A) – Short-circuit thyristor or external noise during
the ramp and after full voltage.
• 10 ‘SCR Shorted’ (Thyristor Sensing Trip Type B) – Short-circuit thyristor during the ramp. Motor-side
phase loss during the ramp.
• 11 ‘Low Current’ – Output current falls below a previously set level (P28 ‘Low Amps Level’) for a
specified time (P29 ‘Low Amps Time’). Active only during the running stage.
• 12 ‘C/L Time Out’ – During start-up ramp, output current exeeds the ‘Current Limit’ level (P30) for
the time specified in ‘Limit Time Out’ (P31).
• 13 ‘Overload’ – Output current exceeds the previously set ‘Overload Level’ (P34) and ‘Overload
Delay’ time (P35). Active in all stages of operation. (See section 5.4.5, “Overload Explanation
Diagram”.)
• 14 ‘Shearpin’ – Output current exceeds the previously set ‘Shearpin Level’ (P32) for a time set in
‘Shearpin Time’ (P33). Active only during the running stage. (See section 5.4.5, “Shearpin
Explanation Diagram”.)
• 15 Unused
• 16 ‘User’ – A trip which can be triggered by the customer via a variety of means, e.g., through the
serial comms or via a programmable input.
• 17 ‘Comms Timeout’ – No communication on the serial connection for more than five seconds.
