82• fourth bit = 1 indicates that the alarm should be read andprocessed by an alarm printer interface (an optional mod-ule) or ServiceLink™ modules.The RE-ALARM time is a time period after which, if a preex-isting and previously broadcast alarm has not been cleared, itwill be rebroadcast on the CCN network. See Fig. 41.Other Tables — The CONSUME, NET_OPT, and RUN-TIME screens contain parameters used with a CCN system.See the applicable CCN manual for more information on thesescreens. These tables can only be defined from a CCN Build-ing Supervisor.Perform a Control Test — Check the safety controlsstatus by performing an automated control test. Press theSTOP button on the ICVC to place the chiller in STOP mode.The CONTROL TEST screen can only be accessed when thechiller is in STOP mode. Access the CONTROL TEST tableand select a test to be performed function (Table 15).The Automated Control Test checks all outputs and inputsfor function. In order to successfully proceed with the controlstest, the compressor should be off, no alarms showing, andvoltage should be within ±10% of rating plate value. The com-pressor can be put in OFF mode by pressing the STOP push-button on the ICVC. Each test asks the operator to confirm theoperation is occurring and whether or not to continue. If an er-ror occurs, the operator can try to address the problem as thetest is being done or note the problem and proceed to the nexttest.Table 15 — Control Test Menu FunctionsLEGENDNOTE: During any of the tests, an out-of-range reading will have an asterisk(*) next to the reading and a message will be displayed if the diffuser control isenabled.11 0 1 0 0 0 0Alarm Printer Interface ModuleAutodial GatewayLocal Building Supervisors(s)or ComfortWORKSunusedALARM CONTROLALARM ROUTINGThis decision determines which CCN system elements will receiveand process alarms sent by the CSM. Input for the decision consistsof eight digits, each of which can be set to either 0 or 1. Setting adigit to 1 specifies that alarms will be sent to the system elementthat corresponds to that digit. Setting all digits to 0 disables alarmprocessing. Digits in this decision correspond to CCN systemelements in the following manner:NOTE: If your CCN does not contain ComfortWORKS® controls ora Building Supervisor, Autodial Gateway, or APIM to serve as analarm acknowledger, set all digits in this decision to 0 in order toprevent unnecessary activity on the CCN Communication Bus.Allowable Entries 00000000 to 111111110 = Disabled, 1 = EnabledDefault Value 10000000Fig. 41 — Alarm Control and Alarm Routinga19-1627TESTS TO BEPERFORMED DEVICES TESTED1.
