2-2 Commissioning Box and Switch
B. Verification of SLS operation
1. Turn all SLS switches to the ON position.
2. Check the machine to see that damage or injury will not occur if the
machine is started.
3. Energize the motion bus that the SLS box contactor controls.
4. Check for machine operation and by operating with the normal start
and stop functions. Check to see that the signals to the PLC and
drive are correct. Leave machine in the stopped mode.
5. Observe LEDs in SLS box for the following conditions:
• Power supply DC ON = on.
• VSR — POWER = on.
• Safety relay 1SR — POWER ON, CH1, CH2, K1, K2 = on.
• Safety relay SR — POWER ON, CH1, CH2, K1, K2 = on.
• LED terminal blocks — PLUS = on, 12 = off, MINUS = on.
6. All SLS switch SAFE lights should be off.
7. Check voltage on secondary of CCT.
8. Measure DC voltage on power supply output. If necessary, adjust to
27V.
9. One at a time, check the operation of each SLS switch by turning it
to the OFF position. Then check for the following:
• SAFE light on.
• IC dropped out.
• 1CR dropped out (refer to cross bar).
• Safety relay dropped out, LED — POWER ON = on, CH1, CH2,
K1, K2 = off.
• VSR indicates safe condition. LED — POWER = on, six phase
voltages = off.
• LED T.B. — PLUS = on, 12 = on, MINUS = on
C. To provide an indication of tampering, seal the SLS box, the
SLS switches and the Harting connectors with a tamper-resistant
indicating seal. There are holes in the right hand side of the enclosures
for this and in the Harting connectors.
D. A service log shall be kept for each SLS box that keeps track of the
following:
1. Serial number of SLS box
2. Date of commissioning
3. Name of SLS commissioning technician
4. Name of the SLS service technician
5. Description of service performed
6. Date of service
