9.4 Setpoint Outputs
Two setpoint outputs are available as open-collector transistor transistor logic (TTL) level outputs for driving
relays on the RS-232 option. The outputs are available on the circular connector on the rear of the scale
marked “setpoint” and are configured by setting SPEC15 bit 2 and SPEC16 bits 0–3. See Section 6.0 for more
information about configuring SPEC codes.

Example 1
• Example 1 uses a standard quantity setpoint
of 1000 pieces (SP2) with a percentage pre-
alarm of 90 percent or 900 pieces (SP1).
SPEC16 must be set at 0000.

arrangement where SP1 is 500 pieces and
SP2 is 400 pieces. SPEC16 must be set at
0100.
Example 3
• Example 3 uses an alarm set for 120 percent
(SP2) of 1000 pieces (SP1). SPEC16 must
be set at 0000.
