Dwyer Instruments One-Touch 616OT Series Installation And Operating Instructions

The Series 616OT One-Touch
an extremely versatile transmitter for monitoring pressure. The Series
616OT senses the pressure of air and compatible gases and sends a
standard 4-20 mA output signal. The single button simultaneous calibra-
tion of both zero and span reduces product installation and set up time.
INSTALLATION
Mounting:
The transmitter should be mounted on a vertical surface with the con-
nections directed down to prevent moisture from entering either the
pressure ports or the electrical cable entry.
Electrical Connection:
2-Wire Operation:
CAUTION: DO NOT EXCEED SPECIFIED SUPPLY
VOLTAGE RATINGS. PERMANENT DAMAGE NOT
COVERED BY WARRANTY WILL RESULT. 2-WIRE
UNITS ARE NOT DESIGNED FOR AC VOLTAGE OPER-
ATION.
