    I have a Polar 137 and the clamp is not working.

    Any idea why the clamp is not falling down. is this the problem with the solenoid not energize.

    Please help.

    Hi sir:

    I am recommending 1) test the following power supply in the CU: A) +5vDC B) +24vDC C)+42vDC D)-12vDC E) -30vDC

    2) The tolerance will be 0.7% up or down, otherwise repair or replace, the clamp does NOT coming down.

    3) if everything is right: test a) Solenoid YSB:+42vDC B) Solenoid Y27+42 For clamp. C) Cut buttom S28a+b=+24Vdc

    Let me know, what model is the POLAR 137 exactly
