14. P8 – DEADBAND Set Point Models Only

This register is found on the SetPoint model only. It sets the adjustable deadband for the SPDT relays.
Deadband can be set to 0%, 0.1, 0.2, 0.5, 1, 2, 5 and 10% of full scale. The relay will energize precisely at the
value in its corresponding P6 and P7 registers on increasing pressure. The relay will de-energize at a value
equal to the corresponding P6 and P7 register, minus the deadband value, on decreasing pressure. With a 0%
deadband setting, the relays will energize and reset precisely at the values in the corresponding P6 and P7
registers. During programming, the choices found in the register correspond to the actual deadband values in
percent full scale.
