10COUNTERWEIGHT GUIDELINESCounterweight requirements depend on the weight and length of the gate arm, and on the weight and position ofthe arm coupling or conversion bracket. The counterweights listed in the tables below are based on new Safetranarms, conversion bracket and adapter.--NOTE: If using a gate protection device, refer to counterweight tables Appendix A.Counterweights can be mounted on a single counterweight support arm for arms up to 22'. Longer arms requirecounterweight supports on both sides of the mechanism.Horizontal torque. Set horizontal torque to 100 ±20 foot-pounds at counterweight side as follows:1. Close test terminal A (pos. 6) to lower arm to horizontal.2. Place torque wrench (see page 12) over the ½” hexagon end of the motor shaft (or attachscale to arm as shown page 11).3. Holding the torque wrench firmly, release the brake by opening test terminal B (pos. 4).4. Allow wrench to rotate slowly, then hold steady and read torque. Do not rotate the wrenchagainst the torque direction as a false high reading will result.5. Close test terminal B (pos. 4), remove torque wrench and adjust counterweights as needed.Vertical torque. Set vertical torque to obtain a free position of 70° to 83° as follows:1. Close test terminal A (pos. 6) to lower arm to horizontal.2. Open test terminal B (pos. 4) allowing arm to raise to a free balanced condition.3. Check position of arm per diagram page 11 and adjust counterweights for vertical torque toobtain an arm position of 70° to 83°.4. Repeat steps 1, 2 and 3 as required allowing for arm up momentum. Close test terminal B.Note: The free or “default up” position is based on 70° minimum to clear roadwayand 83° maximum so as to not close contact #9.T ORQUE ADJUSTMENTSCounterweightsRequiredShortShort070757-30XStandard070757-26XStud Plate12 – 14 3 (2+1XT) 6 1 115 – 18 4 8 1 119 – 22 5 10 1 123 – 28 6 12 2 229 – 32 7 14 2 233 - 36 8 16 2 237 - 40 9 18 2 241 - 44 10 20 2 245 -46 11 22 2 2Counterweightsmounted on twoSupport ArmsCounterweight Requirement Model S-40EXIT(Standard arms, conversion bracket and adapter)(+1XT)= One counterweight extended up with support bracket and hardware #070925-4X.-- See diagram Appendix A |
