The dual proportional relay configuration is
primarily designed to control external metering
pumps. Setpoints, deviation ranges, and maxi-
mum pulse rates are selected via the relay menu.
• Setpoint: pH value at which relay pulsing be-
gins. Relay 3 setpoint must be less than or
equal to relay 4 setpoint.
• Deviation: Number of pH units from setpoint to
maximum pulse rate. Deviation values cannot
extend beyond the 0 to 14 pH scale.
• Pulse Rate: Pulse rate selected from 0 to 120
pulses per minute maximum.
