NOTICE
Equipment Damage - Precautions for Setting Control Circuit Logic Inputs Jumpers
J4, J5, J6, J7, J8 and J9
Place all jumpers, J4, J5, J6, J7, J8, J9, in the same matching positions for the correct logic input voltage at PCB A2
terminal TB1. Failure to comply will result in E7 control circuit damage or in damage to connected peripheral devices.
J4, J5, J6, J7, J8, J9 jumpers are placed in factory default positions 1 & 2 for 120 Vac Control Circuit Logic Inputs.
Equipment Failure to Operate - Precautions for Safety Circuit Installation
TB1-1 to TB1-9
Install a jumper or a normally closed (N.C.) circuit at PCB A2 terminals TB1-1 to TB1-9 to allow drive or bypass
operation and to prevent a Safety Open fault at power-up. Failure to comply will prevent drive or bypass operation.
Equipment Failure to Operate - Precautions for BAS Interlock Circuit Installation
TB1-3 to TB1-9
Install a jumper or a normally closed (N.C.) circuit at PCB A2 terminals TB1-3 to TB1-9 to allow drive or bypass
operation and to prevent a Safety Open fault at power-up. Failure to comply will prevent drive or bypass operation.
