Relays

Functions affected by setpoint are configured by parameters that determine the

application requirements such as timing. P111 Pump and Control functions (see page 127

sets the function requirements. Other function parameters:

• P132–Pump Start Delay

• P133–Pump Power Resumption Delay

• P645–Relay Duration

Relay Logic is Modified

Normal operating conditions means that alarms are off and pumps are on. This can be

reversed using P118–Relay Output Logic.

Relay Failsafe

P129–Relay Failsafe

Adjusts how individual relays react to a failsafe condition. Relays can be set to:

• OFF Control is by P071–Failsafe Material Level

• HOLd Keeps the relay in the current state

• dE De-energizes the relay (default for pump controls)

• En Energizes the relay

Preset Applications

Preset applications set up the relay parameters to predetermined values shown below:

Value # Parameters Affected

Off 0 All relays set to OFF

Wet Well 1

Pump down with the following settings:

P111 52 52 1(H) 1(L) 0 0

P112 70% 80% 90% 10% – –

P113 20% 20% 85% 15% – –

Wet Well 2

Pump down with the following level and rate settings:

Parameter

Relay #

123456

P111 52 52 1(H) 1(L) 0 0

P112 70% 80% 90% 10% – –

P113 20% 20% 85% 15% – –

P121 1

Because the pumps are started by rate, you must change P703 to desired

empty rate.
