SWITCH 6: ON -Will fire relay if gate is pushed UP from closed limit, used with clutch option. Also ANTI TAIL-GATE ALARM, if tailgating is detected by close loop, K1 relay will fire. When using clutch option, turning on S1-6 & S2-7, gate will close by timer whenever forced up. SWITCH 7: Used to enable arm to work in reverse direction, see page 9. SWITCH 8: Off will make K1 relay activate during open cycle (use with buzzers, counters, etc. ). On will pulse K1 relay when OPEN LIMIT (OLS) is reached (activates a swing or slide gate its lane).

The slow stop ramp time is fixed but can be overrun by the fast run time if not adjusted properly. When adjusting make sure the slow stop ramp completes before the close limit. Changing settings will adjust fast run timer by 1/8 second increments. #2 and #4 on equals 1. 25 seconds, etc. ) 1 1 J2 D8 S1 R1 MANUAL M/S 1 2 3 4 5 6 7 8 9 1Ø 11 12 AUX LIMITS D1Ø 1 2 3 4 5 6 7 8 J3 6 7 8 Q2 OPEN R14 R18 R17 S3 J5 U18 T2 T1 D15 D16 D17 T4 T3 D18 D19 T6 T5 D22 T8 T7 D23 D24 R61 R53 S2 R12 1 2 3 4 5 R16 C3 C19 U4 CLOSE R21 OPEN 1 OPEN 2 OPEN 3 AUX 4 SAFETY 5 CLOSE 6 BACK 7SHADOW 8 C16 R24 R3Ø R35 R36 R41 R42 R46 U13 R47 R5Ø U14 U8 U9 U11 U15 F5 C2 C1 U1 C2 R23 OLS D7 OPEN D6 BRAKE D5 CLOSE D4 R7 CLS D3 R6 IRD D2 R5 U2 R19 + C5 + R2 K1 R11 HBEAT D11 U19 Aux Relay BAT LO AC POWER D14 R13 BAT­ MOV D12 B1 R2Ø R15 R4 R3 Q1 D9 U3 C4 CPU R1Ø R9 R8 U5 U7 X2 X1 U6 R22 R26 R34 R33 R4Ø R39 R45 R44 R43 D21 R49 R48 R43 R6Ø C22 R59 IRD1 C7 C6 R63 R58 D27 DX3 R25 C12 U12 U1Ø U16 Q6 Q5 DX4 R57 C13 R56 R38 R37 D2Ø R51 DX2 D29 JP2 Q4 D28 CLOSE TIMER - SWITCH PACK S2 (1-5) NOTE: Default setting is off. On the MEGA ARM the switches 1-5 on S2 are for the closing time delay to select the period of time that the gate stays open after the obstruction sensor has reversed and re-opened the arm or if the S2-7 timer to close is turned on. The default will keep the gate up for 4 seconds to allow the vehicle to be moved from the gate arm path. Changing settings 1 - 5 will increase or decrease this hold open time. The default of 3 ON and 1, 2, 4, 5 OFF will provide a 4 second close time delay.

(WARNING: Special care should be used to avoid arm from closing on cars. Use safety loops, stop loops, photo beams and a long enough time delay. ) NOTE: Can be used with multiple vehicle memory buffer to allow gate to close and reset count memory to zero.
