4 COLD WA TER ST AR T Before arriving at the job site to begin the installation, it's important to first inspect the system and determine what materials you will need. Some parts are includ- ed with the controller while others you will need to provide.
5 Connecting P ow er to the Controller Supply power from the 120 V AC power input from the heater to the controller power inputs T erminal Block (TB1). This is accomplished by connecting wiring from the control box to the heater TB1 board 120 V AC power input connections.
6 Cold Star t Sequence of Operation 1) 120V AC to heater sends 120V AC to Cold Start control on terminal block 1. 2) 120/24V AC transformer and 120V AC-12VDC con- verter are powered.
7 NO TE: Elodrive actuator is Nema 4 rated. TR OUBLESHOO TING Check your power source using a V olt-Ohm meter; check the following voltages at TB1 terminal block: TB1-1 to TB1-2 = 108 V AC Minimum, 132 V AC Maximum TB1-1 to TB1-3 = 108 V AC Minimum, 132 V AC Maximum TB1-2 to TB1-3 = Must be less than .
