Trimpot Adjustments - KB Electronics Penta Power KBVF Series Installation & Operation Manual

12.1 Power On (PWR) – The "PWR" LED will illuminate green when the AC line is applied to the drive.
12.2 Status LED (ST) – The "ST" LED is a tricolor LED which provides indication of a fault or
abnormal condition. The information provided can be used to diagnose an installation problem
such as incorrect input voltage, overload condition, and drive output miswiring. It also pro-
vides a signal which informs the user that all drive and microcontroller operating parameters
are normal. Table 4, on page 38, summarizes the "ST" LED functions.
Note: The drive is factory set to the Automatic Start Mode. For Manual Start/Rest, see
Section 9.6, on page 33.

13 TRIMPOT ADJUSTMEnTS

The drive contains trimpots which are factory set for most applications. See Figure 4, on page 20,
for the location of the trimpots and their approximate factory calibrated positions. Some applications
may require readjustment of the trimpots in order to tailor the drive for a specific requirement. The
trimpots may be readjusted as described below.
WARnInG! If possible, do not adjust trimpots with the main power applied. If
adjustments are made with the main power applied, an insulated adjustment tool
must be used and safety glasses must be worn. High voltage exists in this drive. fire and/or
electrocution can result if caution is not exercised. Safety Warning, on pages 8 and 9, must
be read and understood before proceeding.
