Setting Pulse Input Type (PULSE.IN)
Seven input types may be set for the pulse input, and it may be disabled. See Pulse Input specifications
on page 11.
The pulse input is disabled with factory settings.
Press Enter to access the menu then press the Up to scroll through the flashing choices. Press Enter to
accept the setting. Press Menu to back out of a menu, or hold Menu to exit at any time.
The following input types may be selected.
Input Selection Input Type Description
ACTIVE Active External power supply driven pulse inputs
NPN NPN Internal pull-up resistor on S+ for NPN inputs
PNP PNP Internal pull-down resistor on S+ for PNP inputs
REED Reed Internal pull-up resistor on S+ for switch inputs
COIL Coil
Magnetic coil flowmeter inputs
Note: Input selector switch must be set to mV
ISO Active, Isolated
External power supply driven isolated pulse inputs.
Note: Input selector switch must be set to ISO
ACTLO Active, Low External power supply driven pulse inputs with a low threshold
NPNLO NPN, Low
Internal 3 V pull-up resistor on S+ for NPN inputs with a low
threshold
PNPLO PNP, Low
Internal pull-down resistor on S+ for PNP inputs with a low
threshold
DISABLE Disable Input
Disable the pulse input and all pulse input related features includ-
ing rate, total, and grand total features
Input Level Selection Switch
In addition to programming the PULSE.IN parameter, the input selector switch shown below must also be
set. Input voltage level selections include mV, V and isolated voltage level inputs.
See Pulse Input Signal Connections on page 20 for details on wiring the input types.
