Vi 8 J Motor Protector / Power Monitor Digital Three Phase. installation and Operation Instructions WAGNER KEY FEATURES v Digital voltmeter displays instantaneous line voltage for all 3 phase pairs v Contractor load side monitor checks for contractor closure + One button contractor load side voltage measurement « Automatic voltage tester adjusts from 160 to 600 volts + Adjustable response timer (0.1 to 20 sec.) prevents nuisance ripping v Adjustable delay on break (DOB) timer (0 to 720 sec.
remains outside the tolerance after the response time has elapsed, the DTP-3 will turn off its output relay and protect your device. When the DTP-3's relay opens, the delay timer starts, This timer keeps track of the time since the output was turned off and prevents the protected equipment from restarting too soon. The delay is also user adjustable. iris particularly useful for the protection of of compressor contractor, The DTP-3 should be mounted on a metal surface with four #8 sheet metal screws.
load side to the DTP-3's T1, T2 and T3 terminals. Nate that the load side monitoring should also include the required fusing to meet ~ the branch circuit protection requirements of the National Electric Case or locale equivalent. If installed, the contractor fault option should bs sett “ON”, © Nanosecond COM These terminals connect to the relay output. The relay closes when the line voltage is within the selected tolerance, the control voltage is on and the delay timer has expired.
imbalance Voltage Tolerance in % (% IMBALANCE flashes). The value may be adjusted by pressing the up and down arrows. (SECONDS flashes). The value may be adjusted by pressing the up and down arrows. (This is the delay on break timer value) Delay time in seconds (DELAY SECONDS flashes). The value may be adjusted by pressing the up and down arrows. This is the Random Start Delay value. (This is a delay on make timer) Response lime in seconds and tenths of seconds (RESP.
