Parameters
Negative Logic
When P118 = 3 (negative logic), the operation for the indexed relay is reversed from
normal.
P119 Relay Logic Test
Forces the relay control logic into an ACTIVATED or DE-ACTIVATED state.
This parameter tests site wiring and control logic programming. Forcing the relay to an
activated or de-activated state is similar to the MultiRanger detecting an event and
responding to it. Helpful in testing new installations and diagnosing control problems.
Pump Setpoint Modifiers (P121 and P122) [MR 200]
Please note that these parameters apply to the MultiRanger 200 only.
These parameters provide alternate ways of starting the pumps in the pump group. See
the
Pump Control
section on page 57 for descriptions of the pump control algorithms.
P121 Pump by Rate [MR 200]
Sets the pump relays to accept control by rate of level change once the first ON setpoint
is reached.
Use this function when multiple pumps are to be controlled by rate of level change rather
than by setpoints.
The delay between pump starts is set by P132 Pump Start Delay.
This only applies to any relays set to pump control (P111 = 50 to 56).
