Cooler Pump Sequence of Operation — At any- time the unit is in an ON status, as defined by the one of the following conditions, the cooler pump relay will be enabled.

1.The Enable-Off-Remote Switch in ENABLE, (CTRL=0).

2.Enable-Off-Remote Switch in REMOTE with a Start-Stop remote contact closure (CTRL=0).

3.An Occupied Time Period from an Occupancy Schedule in combination with items 1 or 2 (CTRL=2).

4.A CCN Start-Stop Command to Start in combination with items 1 or 2 (CTRL=3).

As stated before, there are certain alarm conditions and Operating Modes that will turn the cooler pump relay ON. This sequence will describe the normal operation of the pump control algorithm.

When the unit cycles from an “On” state to an “Off” state, the cooler pump output will remain energized for the Cooler Pump Shutdown Delay (Configuration→OPT1→PM.DY). This is configurable from 0 to 10 minutes. The factory default is 1 minute.

NO INTEGRAL PUMP — SINGLE EXTERNAL PUMP CONTROL — With a single external pump, the following options must be configured:

•Cooler Pump Control (Configuration→OPT1→CPC) = OFF.

•Cooler Pump 1 Enable (Configuration→OPT1

→PM1E) = NO.

•Cooler Pump 2 Enable (Configuration→OPT1

→PM2E) = NO.

The maximum load allowed for the Chilled Water Pump Starter is 5 VA sealed, 10 VA inrush at 24 volts. The starter coil is powered from the chiller control system. The starter should be wired between LVT-25 and LVT-21. If equipped, the field- installed chilled water pump starter auxiliary contacts should be connected in series with the chilled water flow switch.

The Cooler Pump Relay will be energized when the machine is “On.” The chilled water pump interlock circuit consists of a chilled water flow switch and a field-installed chilled water pump interlock. If the chilled water pump inter- lock circuit does not close within five (5) minutes of starting, an A200 — Cooler Flow/Interlock Failed to Close at Start-Up Alarm will be generated and chiller will not be allowed to start.

If the chilled water pump interlock or chilled water flow switch opens for at least three (3) seconds after initially being closed, an A201 — Cooler Flow/Interlock Contacts Opened During Normal Operation Alarm will be generated and the ma- chine will stop.

NO INTEGRAL PUMP — DUAL EXTERNAL PUMP CONTROL — With two external pumps, the following options must be configured:

•Cooler Pump Control (Configuration→OPT1→CPC) = ON.

•Cooler Pump 1 Enable (Configuration→OPT1

→PM1E) = YES.

•Cooler Pump 2 Enable (Configuration→OPT1

→PM2E) = YES.

The maximum load allowed for the Chilled Water Pump Starters is 5 VA sealed, 10 VA inrush at 24 volts. The starter coil is powered from the chiller control system. The starter for Chilled Water Pump 1 should be wired between LVT-25 and LVT-21. The starter for Chilled Water Pump 2 should be wired between LVT-24 and LVT-21. A field-installed chilled water pump interlock for each pump must be connected to each pump’s interlock points on the main base board. The chilled water pump 1 interlock, CWP1, must be connected to MBB- J7-1 and –2. The chilled water pump 2 interlock, CWP2, must be connected to MBB-J7-3 and –4. The chilled water pump

interlock contacts should be rated for dry circuit application capable of handling 5 vdc at 2 mA.

SINGLE INTEGRAL PUMP CONTROL — With a single pump, the following options must be configured:

•Cooler Pump Control (Configuration→OPT1→CPC) = ON.

•Cooler Pump 1 Enable (Configuration→OPT1

→PM1E) = YES.

•Cooler Pump 2 Enable (Configuration→OPT1

→PM2E) = NO.

With a single integral pump, the Cooler Pump Starter will be energized when the machine is occupied. As part of the factory-installed package, an auxiliary set of contacts is wired to the MBB to serve as Chilled Water Pump Interlock. When the mechanical cooling is called for, the pump interlock and flow switch is checked. If the circuits are closed, the machine starts its capacity routine. If the auxiliary contact interlock does not close within 25 seconds of the ON command, a T190 — Cooler Pump 1 Aux Contacts Failed to Close at Start-Up Alert will be generated and the pump shut down. The unit will not be allowed to start. If the chilled water flow switch does not close within one (1) minute, two alarms will be generated. A T192 — Cooler Pump 1 Failed to Provide Flow at Start-Up Alert and an A200 — Cooler Flow/Interlock Failed to Close at Start-Up Alarm will be generated and chiller will not be al- lowed to start.

If the chilled water flow switch opens for at least 3 seconds after initially being closed, a T196 — Flow Lost While Pump 1 Running Alert and an A201 — Cooler Flow/Interlock Contacts Opened During Normal Operation Alarm will be generated and the machine will stop.

If the control detects the chilled water pump interlock open for 25 seconds after initially being closed, a T194 — Cooler Pump 1 Contacts Opened During Normal Operation Alert is generated and the unit is shut down.

If the control detects the chilled water flow switch circuit closed for at least 5 minutes with the pump output OFF, an A202 — Cooler Pump Interlock Closed When Pump is Off Alarm will be generated and the unit will not be allowed to start.

If the control detects that the chilled water pump auxiliary contacts are closed for at least 25 seconds while the pump is OFF, a T198 — Cooler Pump 1 Aux Contacts Closed While Pump Off Alert is generated. The chiller will not be allowed to start.

If the control starts a pump and the wrong interlock circuit closes for at least 20 seconds, an A189 — Cooler Pump and Aux Contact Input Miswire Alarm will be generated. The unit will be prevented from starting.

As part of a pump maintenance routine, the pump can be started to maintain lubrication of the pump seal. To utilize this function, Cooler Pmp Periodic Start (Configuration→OPT1 →PM.P.S) must be set to YES. This option is set to NO as the factory default. With this feature enabled, if the pump is not op- erating, it will be started and operated for 2 seconds starting at 14:00 hours. If the pump is operating, this routine is skipped. If the pump has failed and an Alarm/Alert condition is active, the pump will not start that day.

DUAL INTEGRAL PUMP CONTROL — With a dual inte- gral pump package, the following options must be configured:

•Cooler Pump Control (Configuration→OPT1→CPC) = ON.

•Cooler Pump 1 Enable (Configuration→OPT1

→PM1E) = YES.

•Cooler Pump 2 Enable (Configuration→OPT1

→PM2E) = YES.

Pump Start Selection is a field-configurable choice. Cooler Pump Select (Configuration→OPT1→PM.SL) is factory defaulted to 0 (Automatic). This value can be changed to 1
