The Relay Set Pt section defines each of the parameters.

When this menu is accessed, the display shows all setpoints assigned to the current channel. A typical display
looks like this:
SP2 Output Chan
Slot 03 Chan # 02
• SP2 is the setpoint label.
• Slot 03 is the slot number where the Relay Output PCB resides.
• Chan # 02 is the relay channel of the setpoint on the Relay Output PCB.
Pressing any key other than the Esc or Scan/Hold Key cycles through the reports for all other assigned setpoints
for this channel.

This menu is used to select the setpoint to be set up for the displayed channel. Setpoints can be established for
monitoring channels and also for math channels. Up to eight setpoints can be assigned per channel, labeled SP1
for setpoint 1 through SP8 for setpoint 8.
Set has four submenus for level and five submenus for flow:
• Value — once you have selected a setpoint to set up, the activation value, the point where the setpoint
relay changes state, can be entered. This value is entered directly with the Alphanumeric Keys or
scrolled to with the Arrow Keys. The “-“ Key is used to toggle between the positive and negative value of
the number entered.
• Dead — the deadband value determines the point at which a setpoint relay returns to its normal on/off
state after the relay has been activated. The deadband value equals the change in the measured
parameter before the setpoint relay returns to its normal state. Kistler-Morse recommends the use of a
non-zero deadband to prevent relays from oscillating. The value is entered directly or scrolled to with the
Arrow Keys.
• Hi/Lo — setpoint relays can be configured to change state either above (Hi) or below (Lo) the setpoint
value (Value).
• Echo Loss Mode — if the UltraWave Series detects an echo loss that lasts longer than a threshold time,
one of three fail-safe conditions can be applied to a setpoint: On, Off, No Change. The On setting
energizes the setpoint. The Off setting de-energizes the setpoint and the No Change setting means no
change is made to the setpoint condition. No Change is the default.
• Mode — (Flow Only) This menu sets up how the setpoint relays are going to be activated and used.
There are five choices for Mode:
1. Flow relay activation is based on the flow rate - for example, CFS, GPS, etc. With this selection the relay
can be programmed to control a dosing pump for a chlorine system or pace a wastewater sampler.
2. Head relay activation allows the relay to be activated based on the head (level)- for example, ft, in, m, etc.
3. Rate relay activation is based on total flow - for example CF, GL, etc. With this selection, the relay can
