Emission Range Selection (Sh4-X-Xxxx-X Models Only) - Datasensing SH4 STANDARD MUTING Product Reference Manual

FUNCTIONS

EMISSION RANGE SELECTION (SH4-X-XXXX-X models only)

On Body models only (SH4-X-XXXX-X), TEST input (Pin 2 on transmitter unit) may be
used to set the Emission Range.
By default, SHORT Range is selected. To toggle between SHORT and LONG range, follow-
ing procedure must be followed: at runtime keep pin 2 input connected to 24V for more
than 2s and less than 5s to change range setting from Long to Short or viceversa. Emis-
sion Range setting is kept also after a power cycle.
TEST

Range Change Request
If a falling edge is detected within 5s from rising edge, emitter unit reboots with the new
range.
If a falling edge is not detected within 5s from rising edge emitter unit locks into Range
setting failure Lockout without any change on range setting.
