a. All voltage measurements are referenced to common ground on pins 2 and 14.
b. For color pairs, the first named color is the predominant color; the second named color is the spiral stripe around it.
c. This pin is also used as the Serial Data Input for use with PC connections. Cable 69-4704-042 is recommended instead
for a serial data connection. See section 4.3.2.
d. Output from internal driver is current limited to 100 mA maximum. The output between the alarm pin and ground can drive
low-power alarm devices rated for 5 VDC. Control higher-power (>100 mA) devices, or devices with different voltage re-
quirements through a user-supplied relay. See section 3.3.8 to configure alarm conditions.

+12.5 VDC, 1 ampere maximum. Power for external
devices.
Common ground
25 millisecond (minimum) pulse, +5 to +15 VDC
For use with PC connections. Cable 69-4704-042 is
recommended. See section 4.3.2.
3 second, +12 VDC pulse at beginning of sample
collection
Ground this input (short to pin 2) to disable sampler
operation. Leave this input open (floating) to collect
samples.

devices.
Alarm Off = 0 VDC, Alarm On = +5 VDC
Alarm Off = 0 VDC, Alarm On = +5 VDC
Alarm Off = 0 VDC, Alarm On = +5 VDC
Alarm Off = 0 VDC, Alarm On = +5 VDC
Linear current loop signal representing minimum
flow rate at 4 mA, maximum flow rate at 20 mA.
This input is paired with pin 13.
See pin 12.
